Added new tool `bin/gen-years.sh` to form the top level file `years.html`
using `.top`, `.year` and `.entry.json' files!

Added new tool `bin/gen-authors.sh` to form a new top level file
`/authors.html` from `author/author_handle.json` and related
`.entry.json' files!

The old `winners.html` file now redirects to the new `authors.html` file.

The core logic of converting markdown to HTML has been
generalized into a new `bin/md2html.sh` tool.

The `bin/readme2index.sh` tool now calls the
new `bin/md2html.sh` tool to form entry's `index.html` files.

The `bin/quick-readme2index.sh` tool now calls the new `bin/md2html.sh`
tool, unless the `index.html` is newer than both `.entry.json` and
`README.md`, to form entry `index.html` files.

Increased, slightly, the speed of the `bin/quick-readme2index.sh` tool
with the entry's `index.html` file does not need to be updated.

The `bin/quick-readme2index.sh` tool will touch the `index.html` file,
even if the `bin/md2html.sh` tool determines that the `index.html` file
did not change, so that the `index.html` file will not appear
out of date with respect to `.entry.json`.

Slightly improved the look and feel of `index.html` files for entries.

The logic of `bin/all-run.sh` has been improved.  The initial
processing, from first bash version check, thru the -N test, serves
as the model for the `bin/readme2index.sh` tool and the
`bin/quick-readme2index.sh` tool.  There tools now share
a common set of command line options.

Changed the format of `inc/md2html.cfg` so that for a given "_file_glob_"
match, options follow, one per line.  The "_file_glob_" is on a line
by itself.  The option lines that follow must be intended:

```
[12][0-9][0-9][0-9]/README.md
	-H
	topnav=year
	-o
	bin/subst.default.sh
	-o
	bin/subst.year.sh
```

Added "-D ./" to top level markdown files in `inc/md2html.cfg`.

The above intending is performed with 1 or more whitespace
characters, although we use a leading tab "convention"
out of deference to Makefile formats. :-)

Once a new "_file_glob_" is found, the set of any previous
option lines is said to have ended.

The general argument processing logic now makes used of shell arrays.

Added checks in the `bin/md2html.sh` tool to disallow a "_file_glob_"
of . (dot) as this is used internally to help the shell process the
new `inc/md2html.cfg` format.

Changed `bin/all-run.sh` VERSION from "1.1.2 2024-01-20"
to "1.3 2024-02-11".

Changed `bin/output-index-author.sh` VERSION from "1.3.1 2024-01-16"
to "1.4 2024-02-11".

Changed `bin/pandoc-wrapper.sh` VERSION from "1.3.2 2024-01-19"
to "1.4 2024-02-05".

Changed `bin/quick-readme2index.sh` VERSION from "1.0 2024-01-20"
to "1.1 2024-02-11".

Changed `bin/readme2index.sh` VERSION from "1.1.1 2024-01-20"
to "1.2 2024-02-11".

Changed `bin/subst.default.sh` VERSION from "1.1.1 2024-01-16"
to "1.2 2024-02-05".

Changed `bin/subst.entry-index.sh` VERSION from "1.1.1 2024-01-16
to "1.2 2024-02-11".

Changed `bin/output-index-inventory.sh` VERSION from "1.0.1 2024-01-16"
to "1.1 2024-02-11".

Changed `bin/manifest.entry.json.awk` from "1.0 2024-01-14"
to "1.1 2024-02-11".

Changed `bin/sort.gitignore.sh` from "1.0 2024-02-01"
to "1.1 2024-02-11".

Changed substitution symbol _%%DOCROOT_URL_SLASH%%_ to _%%DOCROOT_SLASH%%_
in various "inc/*.html" files.

Moved setting of symbol _%%DOCROOT_SLASH%%_ from `bin/subst.entry-index.sh`
to `bin/subst.default.sh`.

Changed the variable _$DOCROOT_URL_SLASH_ to _$DOCROOT_SLASH_, in
bin tools that use it, to be more descriptive.

Removed `-P pandoc_opts` from `bin/*.sh` command lines.
The PANDOC_WRAPPER_OPTSTR value is only used in `bin/pandoc-wrapper.sh`.

Removed `-B optstr` and `-A optstr` from the `bin/md2html.sh` command line.

Removed `[-O tool=optstr ..]` from the `bin/md2html.sh` command line.

Removed old use of `-U top_url` from command lines.
Add `-w site_url` as sort of a "replacement" for the old `-U top_url`.

Added a new `-U URL` to `bin/gen-author.sh`, `bin/output-index-inventory.sh`,
`bin/md2html.sh`, `bin/subst.default.sh`, and `bin/subst.entry-index.sh`
to allow for the Nu HTML check can use the encoded absolute URL of
the HTML page.

Added `-t tagline` to most command lines.

Added `-T md2html.sh` to most command lines.

Added `-D docroot/` to most command lines to set DOCROOT_SLASH.
The DOCROOT_SLASH value defaults to "../../" for most in tools,
suitable for HTML files under a `YYYY/dir` directory, except for
`bin/gen-location.sh` and `gen-entries-html.sh` (as this produces a
top level HTML file) and `bin/md2html.sh` (forms files at any level)
who use "./" instead.

In the case of `bin/output-index-inventory.sh`, `bin/quick-readme2index.sh`,
`bin/readme2index.sh`, and `bin/all-run.sh`

Helped make the use of exit code in bin tools a bit more consistent.

Fixed a number of typos in the bin tools.

Added comments for lower level tools such as
`manifest.entry.json.awk`, `bin/subst.default.sh`,
`bin/subst.entry-index.sh`, and bin/`manifest.entry.json.awk` to
indicate how they are usually invoked by other tools.

Changed the comments that a new `bin/md2html.sh` tool (that was the
`bin/readme2index.sh` tool) would add to a entry's `index.html` file.
No longer will it add the tool version number to the comment.  Thus,
a change in tool version will not force all entry `index.html`
files to be modified.  Now both the tool adds two comments, one
is the _tagline_ to indicate how the markdown content was generated,
and one for the new `bin/md2html.sh` tool.  For example:

```
<!-- The original markdown content was formed by the tool: bin/quick-readme2index.sh -->
<!-- The HTML was converted from markdown by the tool: bin/md2html.sh -->
```

Improve the debugging, especially in regards to changing important
exported shell variables, in `bin/md2html.sh`.  Other bin tools
have their exported shell variables improved somewhat as well.

The `bin/README.md` now describes the general _converting markdown
to HTML_ procedure including _getopt phases_ and _HTML phases_.
Content from `inc/md2html.cfg` and `bin/readme2index.sh` that related
to this topic has been centralized into the `bin/README.md` file.

Improved formatting of the `bin/README.md` file.  Updated it as needed
according to the above.

Sorted `2011/.year`, `2018/.year`, and `2019/.year` to be in dictionary order.
Adjusted ${WINNERS} in year Makefile to use dictionary order so
that `make genpath` will produce `.year` files in dictionary order.

FYI: We tested this massive set of changes as best as we could.
     Nevertheless we might have missing something in the JSON changes,
     `.entry.json` renames, manifest updates, code comments, etc.
