That's good.

Yes.

Emacs calls a function of m17n-lib (the underlining shaper
engine), and that function calls Emacs' callback funciton
ftfont_drive_otf. The bug was in incorrect handling of an
argument given to ftfont_driver_otf in some case.
As Arabic characters are displayed without underlining
shaper engine in Emacs 23, this bug was not revealed.
So, it is better to apply the fix to emacs 23 too if we are
going to release 23.5.
