You might find that enclosing a special character in square brackets
serves to quote it in a globbing context. This is likely to work for
[*] and [?], (which have special meanings outside square brackets), and
for []] and [[] (square brackets themselves), but not for [!] (which
currently has no special meaning outside square brackets, but does have
a special meaning as the first character inside square brackets).
Users who have files whose names begin with '!', and who want to mention
such files in ignore lists, could possibly use a construct like [x!] to
work around the quoting problem. This would match either an x or an
exclamation mark. By careful choice of x (e.g. using an asterisk or any
other character that is unlikely to appear in a file name), they could
get almost the desired effect of a pattern that matches the files they
want to match, is unlikely to match files they don't want to match, and
doesn't get interpreted as the new negation syntax.
