patch 8.0.1004: matchstrpos() without a match returns too many items commit https://github.com/vim/vim/commit/8d9f0ef5c6a6f6d19c3d02690e1ee347a70b8452 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Aug 27 13:51:01 2017 +0200 patch 8.0.1004: matchstrpos() without a match returns too many items Problem: Matchstrpos() without a match returns too many items. Solution: Also remove the second item when the position is beyond the end of the string. (Hirohito Higashi) Use an enum for the type.
