Each element of completion-ignored-extensions is matched at the _end_
of the file/directory name of the completion candidates.  So I think
currently what you want is not possible.

Using regexp syntax is not a good idea, IMO, since that would require
to rewrite all the customizations users out there have, to escape the
dot.  But I think we could make a change whereby if an element of
completion-ignored-extensions begins with a slash, that means match at
the beginning.  Then we could have "/.git/" as an element, and that
would ignore only the standard ".git" subdirectories, not any
directory that happens to end in ".git".

WDYT?
