Agreed. I've applied this one as-is.
We may want to add a future spy for other features (but not in this
patch); on my list:
Do all shells that support functions also support unset (I haven't found a
countercase yet, but my search space is not very broad)? If so, we can
kill _AS_UNSET_PREPARE in a few more releases.
Can we always find a shell with $(( )) support (at least cygwin ash
supports functions, but lacks arithmetic and $LINENO)? For now, I'm
thinking of porting at_func_arith into m4sh.
Can we always find a shell with XSI parameter expansion support
(${foo##*/}) (again, my search space isn't very broad)? It would be nice
to borrow from libtool's func_dirname which avoids forking on decent
shells (with the added benefit of handling trailing newline correctly).
