First of all (and I think you'll agree), we have to see how relevant this
bug still is "in the wild". In addition, chasing the origin of this
reference "git blame", I found this:
<http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html>
which shows the bug, albeit annoying, has an easy work around. (And BTW:
thanks Paul for always adding careful pointers in your commit messages!).
So this bug wouldn't be a valid reason for rejecting a shell. OTOH, not
supporting the ${var#pattern} expansion would be a perfectly valid reason
to do so.
