Re: [PATCH] xdiff: Show function names in hunk headers.

Mark Wooding [off-list ref] writes:

The function names are parsed by a particularly stupid algorithm at the
moment: it just tries to find a line in the `old' file, from before the
start of the hunk, whose first character looks plausible.  Still, it's
most definitely a start.

+		    (isalpha((unsigned char)*rec) || /* identifier? */
+		     *rec == '_' ||	/* also identifier? */
+		     *rec == '(' ||	/* lisp defun? */
+		     *rec == '#')) {	/* #define? */

GNU diff -p does "^[[:alpha:]$_]"; personally I think any line
that does not begin with a whitespace is good enough.  In either
way, your patch is good.  Thanks.
