OK, so immediately after I sent this, I found the following in

Regular expressions have the same syntax as those found in the Unix
egrep command.

This is, as far as I can find so far, the only specific explanation of
what regex syntax Apache supports.

FAQ-B states that "We implement a simple subset of Perl's regex
support" which is pretty darned vague.

man egrep has a really good regex explanation. The only question I'm
left with is how to get it to do case-insensitive pattern matching,
since egrep does this with a command line switch (-i) rather than in
the regex itself.

Nothing is perfekt. Certainly not me.
Success to failure. Just a matter of degrees.
