+Subject: Patch 7.3.535
+Fcc: outbox
+From: Bram Moolenaar <Bram@moolenaar.net>
+Mime-Version: 1.0

+Patch 7.3.535
+Problem: Many #ifdefs for MB_MAXBYTES.
+Solution: Also define MB_MAXBYTES without the +multi_byte feature. Fix
+ places where the buffer didn't include space for a NUL byte.
+Files: src/arabic.c, src/edit.c, src/eval.c, src/getchar.c, src/mbyte.c,
+ src/misc1.c, src/screen.c, src/spell.c, src/vim.h
