fix Makefile bugs, improve make help quick_www www, status.html formation

Fixed errors in `1991/davidguy/Makefile`, `2000/bmeyer/Makefile`
and `2012/kang/Makefile` where a multi-line `CSILENCE` make variable
was not properly continued onto the next line.

Improve the output of `make quick_www` and `make www` no be less
verbose and more informative.  Doing this allowed us to uncover
some bugs in the above mentioned entry Makefiles.

The `make quick_www` and `make www` no longer perform a
`make gen_status`.

The `make gen_top_html` rule, via `bin/gen-top-html.sh` will form
`status.html` based solely on the contents of `status.md`.  Only
the `make gen_status` rule will modify `status.md` if needed, and
then rebuild `status.html` if needed.

The `status.html` file was updated to reflect the common way that
`make gen_top_html` forms this file.  The `make timestamp` performs
a `make gen_top_html` after running `make gen_status` so that the
resulting  `status.html` file matches what `make quick_www` and
`make www` would produce.

Changed `bin/gen-top-html.sh` VERSION from "1.4.5 2024-05-19"
to "1.4.6 2024-05-24" to perform the above.

Improved the text written by `make help`.

Added "for $TOOL" to the debug output of `bin/all-run.sh` to
help identify the tool performing the action.

Changed `bin/all-run.sh` VERSION from "1.3.3 2024-04-13"
to "1.3.4 2024-05-24" to perform the above.

Moved `make gen_other_html` after `make entry_index` and after the
`make quick_entry_index` in `make quick_www` and `make www`.

Perform `make quick_www` to perform the above and test under macOS.

Perform `make www` to perform the above and test under macOS.
