By the way, t9010 uses ${#parameter} (strlen) which is bashism we forbid,
and it needs to be rewritten (David CC'ed).

Actually, no. It is perfectly valid POSIX. So we would need this patch.

I know it is in POSIX, but not in the subset we allowed so far. I do not
recall the details offhand, but we must have seen some shell that lacked
it or something.
