Request review libx11 compose seqeunce patch

[Pander]

Hi all,

Please review this patch for libx11 to extend and fix compose key
sequences as was request via GTK+ community a while back. The patch and
extensive comment can be downloaded here:
  https://bugs.freedesktop.org/show_bug.cgi?id=18751#c7

Implementing this will improve overall quality of compose sequences and
consolidate the 413 additional compose sequences currently defined in
gtk+ for GNOME and solving conflicting definitions compared to compose
sequences in Xorg for KDE, etc.

A lot of work has gone in to this and I hope this bug can be solved
soon. Please contact me if I need to amend something to the patch or if
you have any questions.

Thanks,

Pander
