+	* function.c (subst_expand): Valery Khamenia reported a
+	pathological performance hit when doing substitutions on very

+	strlen() a ridiculous number of times.  Instead of having each
+	call to sindex() call strlen() again, keep track of how much of
+	the text we've seen and pass the length to sindex().
