Hi, we have noticed that when you include bracket characters in the filename component of a pathname object (or a string), WILD-PATHNAME-P will return true. 

I knew this is a feature, but... brackets are usually legal characters in filenames in many filesystems, and when dealing with them,  it's really easy to involve bugs. You'll have to use parse-native-namestring to convert such a string to pathname, which forbids the use of other wildcard characters in other places and also encourages writing non-portable code.

I think it is possible to include a boolean variable (in the sb-impl package) to toggle this. When we turn this feature off, we can recognize brackets as normal characters.  It is convenient and doesn't break compability.

Is that a good idea?

Regards,
Charles Lew.
