patch 8.0.0177: BufEnter autocommand not fired for a directory commit https://github.com/vim/vim/commit/e13b9afe1283f5ae43232b5992372a0eb570666c Author: Bram Moolenaar <Bram@vim.org> Date: Fri Jan 13 22:01:02 2017 +0100 patch 8.0.0177: BufEnter autocommand not fired for a directory Problem: When opening a buffer on a directory and inside a try/catch then the BufEnter event is not triggered. Solution: Return NOTDONE from readfile() for a directory and deal with the three possible return values. (Justin M. Keyes, closes #1375, closes #1353)
