+ + fix a check in infotocap which may not have detected a problem when
+ it should have.
+ + add a check in tic for the case where setf/setb are given using
+ different strings, but provide identical results to setaf/setab.
+ + further improve fix for terminfo.5 (patch by Kir Kolyshkin).
+ + reorder loop-limit checks in winsnstr() in case the string has no
+ terminating null and only the number of characters is used (patch
