[PATCH] Fix escaping of glob special characters in pathspecs

[Kevin Ballard <kevin@sb.org>]

match_one implements an optimized pathspec match where it only uses
fnmatch if it detects glob special characters in the pattern. Unfortunately
it didn't treat \ as a special character, so attempts to escape a glob
special character would fail even though fnmatch() supports it.
