OK, I've tested this on a couple of different systems. Seems to work fine
under sh/bash/ksh (assuming you don't have a file matching that pattern in
.,which seems a reasonable bet), but it breaks under csh/tcsh/zsh:
% echo -?0
echo: No match.
So the problem isn't quite as widespread as first suggested, but it's
still broken. I'd only tested this under bash, not having considered the
possibility that the shell might have other plans for the '?'. I agree we
need to continue to offer an alternative to -?[n], and I'm currently
inclined to favor reverting to -h[n].
