Various somewhat interconnected fixes

At least one link in the FAQ was fixed (not to a file but a named
reference). The FAQ has not been checked entirely for broken links
because the changes have got a bit out of hand and an entire make www
will have to be performed due to a problem I discovered doing the below.
Other improvements were made.

When going through the FAQ for broken links another problem was
discovered, one that broke the scripts that rely on jstrdecode(1). These
have been fixed but need further testing with make www. Some index.html files
were modified; for why this can be done without make quick_readme2index
see below on what changed and why it could be done this way.

When going through the FAQ for broken links I discovered some
issues with some entries' synopsis. This means that a number of
index.html and .entry.json files have been updated. The reason the
index.html files could be modified without running the scripts which
would were broken due to the jstrdecode(1) issue (a missing option in
the scripts) is because I used sgit(1). However, a single README.md file
was modified and the index.html file was not modified just yet. That
will happen with make www. The change is not significant, however, so
this should be okay this time. As the next step is a long process I
therefore decided to commit these things to get them out of the way to
try and prevent the commit from being even larger.

Minor fixes in next/try.sh and next/try.alt.sh were also discovered when
going through the FAQ.

Minor typos were made in the FAQ.

The .gitignore file was also updated: with the last change I
accidentally made it so vim swap files without a filename are not
ignored. That means there have to be two vim swap file globs.
