The problem stems from the character 8237 (#o20055, #x202d),
LEFT-TO-RIGHT OVERRIDE.  For some reason, the composition for this
character screws up line wrapping.

For a simpler test case, see the attached file.  The first line uses
character 8237 and is incorrectly wrapped; the second line uses spaces
and is correctly wrapped.

Handa-san, do you have an idea what the problem might be?  If not, I'll
try to debug.
