provide AddDescriptionMatch for mod_autoindex?

[Jeff Trawick]

AddDescription has some unfortunate behavior in matching file names:

"File is a file extension, partial filename, wild-card expression or full filename for files to describe."

Which is it? In fact there is no way to tell mod_autoindex what the user intends, and some obvious desires cannot be satisfied. It would seem useful to specify a regular expression for the file name to eliminate any such questions.

AddDescriptionMatch "some text" '/somefilebybasename$'
AddDescriptionMatch "some text" '^/some/file/by/full/path$'
AddDescriptionMatch "some text" 'somefilebysubstring'
AddDescriptionMatch "some text" '\.somefilebyfullextension$'
AddDescriptionMatch "some text" '\.somefilebyleadingextension'

Here's the PR I was looking at:

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17210
(the reporter didn't realize the substring issue, but unfortunately I can't figure out how to solve his problem with current AddDescription)

But there are also the following:

http://bugs.apache.org/index.cgi/full/8570
(the reporter suggests changing the semantics of AddDescription to achieve certain functions that AddDescriptionMatch would provide)

http://bugs.apache.org/index.cgi/full/8248
(reporter wants to match .h files but has no way to match .h without also matching .html)

http://bugs.apache.org/index.cgi/full/6995
(another substring problem like the new PR 17210... unclear how to solve)

http://bugs.apache.org/index.cgi/full/5814
(.h vs .html problem again)

(I didn't look back any further)
