When using "use_regex: yes" and setting an excludes: without
specifying a pattern: the existing code passes the file-glob '*' to
the regex matcher. This results in an internal invalid-regex
exception being thrown.
This maintains the old semantics of a default match-all for pattern:
but switches the default to '.*' when use_regex is specified.
The code made sense as-is before excludes: was added (2.5). In that
case, it made no sense to set use_regex but *not* set a pattern.
However, with excludes: it now makes sense to only want to exclude a
given regex but not specify a specific matching pattern.
