I have a different view on this issue - IMHO treating "?" as "exactly
one character" is counterintuitive for people familiar with the use of
wildcards: in all popular regular expression languages, and also in
DTD/XML world, a single "?" metacharacter means "zero or one", which
is probably why the original behavior was introduced (or at least it
was more compatible with the use of "?" in other contexts).
Ahh. Well. If "cat?" is a regular expression then it will match "ca"
and "cat". "cat??" is probably not a valid regular expression: the
final ? means "one or zero occurances of t?" which means that it too
matches "ca" and "cat". However, the javadoc defines "?" and its
definition matches the shell glob definition and it's quite clear that
WildcardQuery is not a RegexQuery just from the docs.
I can't comment about the wildcard character a DTD/XML context, I'm not
that familiar with it.
