[PATCH] Enable File::DosGlob to handle arbitray glob patterns

Here's a patch that simplifies passing arbitrary glob
patterns to C< File::DosGlob::glob() > by making it accept an
array reference containing the glob patterns.

Rationale - if you want to DosGlob a path containing both
spaces and backslashes eg.

    C:\Program Files\*

You need to 'escape' it such that it passes thro'
C<Text::ParseWords::parse_line()> in one piece. I currently
use this to cover globbing arbitrary paths:

    sub dosglob {
        require File::DosGlob;
        my $pat = $_[0]; # just handle one pattern
        if ($pat =~ /[ ']/) {
            # escape it such that Text::ParseWords::parse_line()
            #  sees unquoted text
            $pat =~ s|\\|\\\\|g;
            $pat =~ s|([ '])|\\$1|g;
        }
        return File::DosGlob::glob($pat);
    };

..but it seems like overkill.

My proposed change would allow you to simply say:

    File::DosGlob::glob \@glob_patterns
    File::DosGlob::glob ["C:\\Program Files\\*"]

Cheers, alex.

 Extending it to csh patterns is left as an exercise to the reader.
