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)
