The presence of !$ causes execution to proceed to a point where the check for !( was omitted.

It doesn't work because enabling the `extglob' option doesn't cause bash
to tell the history library to not attempt history expansion when it sees
the history expansion character followed by a `('. This will be fixed in
bash-4.0 or soon after.

So it's failing on the first bang? But there is no problem once I
replace !$ with 'dhclient' - usually extglob seems to work fine with the
suppression of history expansion. Or does the presence of !$ somehow
trigger history expansion (normally not run) which then attempts to
history-expand everything?
