+  wildcard_expand works by dividing the wildcard into segments at

+  except the last segment are handled by matching the wildcard
+  segment against all subdirectories of matching directories, and
+  recursively calling wildcard_expand for matches. On the last
+  segment, matching is made to any file, and all matches are
+  inserted to the list.
+
+  If wildcard_expand encounters any errors (such as insufficient
+  priviliges) during matching, no error messages will be printed and
+  wildcard_expand will continue the matching process.
