 Force bsd_glob() to return an error when it encounters a directory it
 cannot open or read.  Ordinarily bsd_glob() continues to find matches.

+Make bsd_glob() return an error (GLOB_NOSPACE) when the pattern expands
+to a size bigger than the system constant C<ARG_MAX> (usually found in
+limits.h).  If your system does not define this constant, bsd_glob() uses
