+**
+**  wildmat pattern matching with Unicode UTF-8 extensions.
+**
+**  Do shell-style pattern matching for ?, \, [], and * characters.  Might not
+**  be robust in face of malformed patterns; e.g., "foo[a-" could cause a
+**  segmentation violation.  It is 8-bit clean.  (Robustness hopefully fixed
+**  July 2000; all malformed patterns should now just fail to match anything.)
+**
+**  Original by Rich $alz, mirror!rs, Wed Nov 26 19:03:17 EST 1986.
+**  Rich $alz is now <rsalz@osf.org>.
+**
+**  April, 1991:  Replaced mutually-recursive calls with in-line code for the
+**  star character.
+**
+**  Special thanks to Lars Mathiesen <thorinn@diku.dk> for the ABORT code.
+**  This can greatly speed up failing wildcard patterns.  For example:
+**
+**	pattern: -*-*-*-*-*-*-12-*-*-*-m-*-*-*
+**	text 1:	 -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1
+**	text 2:	 -adobe-courier-bold-o-normal--12-120-75-75-X-70-iso8859-1
+**
+**  Text 1 matches with 51 calls, while text 2 fails with 54 calls.  Without
+**  the ABORT code, it takes 22310 calls to fail.  Ugh.  The following
+**  explanation is from Lars:
+**
+**  The precondition that must be fulfilled is that DoMatch will consume at
+**  least one character in text.  This is true if *p is neither '*' nor '\0'.)
+**  The last return has ABORT instead of false to avoid quadratic behaviour in
+**  cases like pattern "*a*b*c*d" with text "abcxxxxx".  With false, each
+**  star-loop has to run to the end of the text; with ABORT only the last one
+**  does.
+**
+**  Once the control of one instance of DoMatch enters the star-loop, that
+**  instance will return either true or ABORT, and any calling instance will
+**  therefore return immediately after (without calling recursively again).
+**  In effect, only one star-loop is ever active.  It would be possible to
+**  modify the code to maintain this context explicitly, eliminating all
+**  recursive calls at the cost of some complication and loss of clarity (and
+**  the ABORT stuff seems to be unclear enough by itself).  I think it would
+**  be unwise to try to get this into a released version unless you have a
+**  good test data base to try it out on.
+**
+**  June, 1991:  Robert Elz <kre@munnari.oz.au> added minus and close bracket
+**  handling for character sets.
+**
+**  July, 2000:  Largely rewritten by Russ Allbery <rra@stanford.edu> to add
+**  support for ',', '!', and optionally '@' to the core wildmat routine.
+**  Broke the character class matching into a separate function for clarity
+**  since it's infrequently used in practice, and added some simple lookahead
+**  to significantly decrease the recursive calls in the '*' matching code.
+**  Added support for UTF-8 as the default character set for any high-bit
+**  characters.
+**
+**  For more information on UTF-8, see RFC 3629.
+**
+**  Please note that this file is intentionally written so that conditionally
+**  executed expressions are on separate lines from the condition to
+**  facilitate analysis of the coverage of the test suite using purecov.
+**  Please preserve this.  As of March 11, 2001, purecov reports that the
+**  accompanying test suite achieves 100% coverage of this file.
