-This functionality is equivalent to what is available in C-shells.
+If the user name is not valid or the home directory cannot be determined
+for some reason the pattern is left untouched and itself used as the

+tilde expansion yields to @code{"~homer/bin/*"} and @code{glob} is not
+looking for a directory named @code{~homer}.

+If this flag is used @code{glob} behaves like as if @code{GLOB_TILDE} is
+given.  The only difference is that if the user name is not available or
+the home directory cannot be determined for other reasons this leads to
+an error.  @code{glob} will return @code{GLOB_NOMATCH} instead of using
