patch 8.0.0621: :stag does not respect 'switchbuf' commit https://github.com/vim/vim/commit/8ad80dea089ffeb1a845199c013e9bb4be1cd22e Author: Bram Moolenaar <Bram@vim.org> Date: Mon Jun 5 16:01:59 2017 +0200 patch 8.0.0621: :stag does not respect 'switchbuf' Problem: The ":stag" command does not respect 'switchbuf'. Solution: Check 'switchbuf' for tag commands that may open a new window. (Ingo Karkat, closes #1681) Define macros for the return values of getfile().
