 	  certain zero-length regex replacements ("^", "$", and "^$").
 	  Add a no_sameline parameter to findnextstr(), and set it in

-	  that such regexes are only found once per line. (DLR; found by

+	  that such regexes are only found once per line.  Also change
+	  length_change from a long to an int; size_t is unsuitable due
+	  to its being unsigned. (DLR; found by Mike Frysinger and DLR)
+	  David Benbennick: Add a few minor cleanups to
+	  do_replace_loop().
 - winio.c:
   get_kbinput(), get_accepted_kbinput()
 	- Don't pass in the value of the REBIND_DELETE flag anymore.
