+  *       match() returns TRUE if pattern matches, FALSE otherwise.
+  *       matche() returns MATCH_VALID if pattern matches, or an errorcode
+  *           as follows otherwise:
+  *
+  *            MATCH_PATTERN  - bad pattern
+  *            MATCH_RANGE    - match failure on [..] construct
+  *            MATCH_ABORT    - premature end of text string
+  *            MATCH_END      - premature end of pattern string
+  *            MATCH_VALID    - valid match
+  *
+  *
+  *  A match means the entire string TEXT is used up in matching.
+  *
+  *  In the pattern string:
+  *       `*' matches any sequence of characters (zero or more)
+  *       `?' matches any character
+  *       [SET] matches any character in the specified set,
+  *       [!SET] or [^SET] matches any character not in the specified set.
+  *
+  *  A set is composed of characters or ranges; a range looks like
+  *  character hyphen character (as in 0-9 or A-Z).  [0-9a-zA-Z_] is the
+  *  minimal set of characters allowed in the [..] pattern construct.
+  *  Other characters are allowed (ie. 8 bit characters) if your system
+  *  will support them.
+  *
+  *  To suppress the special syntactic significance of any of `[]*?!^-\',
+  *  in a [..] construct and match the character exactly, precede it
+  *  with a `\'.
