annotate src/ex_cmds.c @ 3326:a9f8dd20a49f v7.3.430
updated for version 7.3.430
Problem: When a custom filetype detection uses "augroup END" the conf
fileytpe detection does not have the filetypedetect group.
Solution: Always end the group and include filetypedetect in the conf
autocommand. (Lech Lorens)

| 4545 * far. | |
