commit-email.pl regex bug

Hello,

I found that the script was not sending mails containing diffs from
files in directories, whose names contain '++'.

The problem is on the line 323:
  $dir =~ s#^$commondir/##;

$commondir is interpreted, which should not. Fix is easy:

  $dir =~ s#^\Q$commondir\E/##;

Apologise for not attaching patch.
