[PATCH] Support \ in non-wildcard .gitignore entries

[Finn Arne Gangstad <finnag@pvv.org>]

If you had an exclude-pattern with a backslash in it, e.g. "\#foo",
this would not work, since git would do a strcmp of the exclude pattern
and the filename. Only wildcard patterns were matched with fnmatch,
which does the right thing with backslashes. We now also treat all patterns
containing backslashes as wildcards.

De-escaping the pattern while reading the .gitignore file is error prone,
since that would break patterns with both backslashes and wildcards.
E.g. "\\*.c" would be translated to "\*.c" before fnmatch got it,
and would change the meaning of the rule dramatically.
