Bug #2625: rdoc patch for Dir.glob
http://redmine.ruby-lang.org/issues/show/2625

Status: Open, Priority: Normal

This makes it more explicit for us poor windows users that Dir.glob cannot use \

Note that perl actually states this"

On MS-DOSish systems, the backslash is a valid directory separator character.[4] In this case, use of backslash as a quoting character (via GLOB_QUOTE) interferes with the use of backslash as a directory separator. The best (simplest, most portable) solution is to use slashes for directory separators, backslashes for quoting. However, this does not match some users' expectations, so backslashes (under GLOB_QUOTE) quote only the glob metacharacters [, ], {, }, -, ~, and \ itself. All other backslashes are passed through unchanged, if you can manage to get them by Perl's own backslash quoting in strings. It may take as many as four backslashes to finally match one in the filesystem. This is so completely insane that even MS-DOSish users should strongly consider using slashes. If you really want to use backslashes, look into the standard File::DosGlob module, as it might be more to your liking than Unix-flavored fileglobbing.

"

perhaps something like that would be considered, as well?
