FWIW, I think the cure is worse than the problem.

And as Michael indicated, a similar problem was
reported in bug #2536.

No simple solution has been found.  The simplistic
one you've (apparently) adopted is, I think, a bad
idea.  Better to just document this (and similarly
for bug #2536) as a limitation of `!' (and `&' and
`M-!').

That at least gives straightforward, if limited,
behavior - easy to understand (but needs to be
documented).  Users can find other ways (e.g.
outside Dired) to take care of such (relatively
corner) cases.

That's unfortunate, but not as unfortunate as the
change you've (apparently) made.

Just one opinion.  Document the limitations, and
leave these two bugs open, hoping that Someone(TM)
at some point will dream up a real, comprehensive
solution.
