           Summary: Allow alternation patterns in std.path.fnmatch
           Product: D
           Version: 1.037
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: wbaxter at gmail.com


It would be nice if fnmatch also supported the standard alternaltion syntax for
wildcards, where "abc.{def,ghi}.jkl" matches either abc.def.jkl or
"abc.gji.jkl".

Attached is a modified version of the function that does that.

Like the current implementation, the additions lack an escape syntax.  So it's
not possible to match filename with a literal ',' or '{'.  (Just like the
current function is unable to match a literal '[', '*' or '?' in a filename)
