Even if that bug is not from bidi, as far as bidi support
suffers from it, the work for bidi support must be suspended
until that bug is fixed.  For instance, please consider the
situation that face-handling code gets unstable at some
point.  If we are working on a bug that bidi-text can't be
displayed by a correct face (just a hypothetical bug), that
work must be suspended.

I understand that merit too.  I even tend to agree on having
the bidi code in the trunk.  I just wanted to point out the
possibility of the above demerit.
