* Match the pattern PATTERN against the string TEXT;
*
* 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
#ifndef FILE_MATCH
* MATCH_LITERAL - match failure on literal mismatch
#endif
* 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 `[]*?!^-\', and
* match the character exactly, precede it with a `\'.
