After a brief walk over the Subversion source I found that probably
the "apr_fnmatch" function is responsible for putting those patterns
in action. Obviously it is part of APR.
Unfortunatelly its docs
(http://apr.apache.org/docs/apr/group__apr__fnmatch.html) are not very
helpful. But the source is -
http://svn.apache.org/viewcvs.cgi/apr/apr/trunk/strings/apr_fnmatch.c?view=markup
.

This is the explaination about the compatibility:
"...
/*
 * Function fnmatch() as specified in POSIX 1003.2-1992, section B.6.
 * Compares a filename or pathname to a pattern.
 */
..."

Anyone with access to that document?
