vim-patch:7.4.2017
Problem: When there are many errors adding them to the quickfix list takes
a long time.
Solution: Add BLN_NOOPT. Don't call buf_valid() in buf_copy_options().
Remember the last file name used. When going through the buffer
list start from the end of the list. Only call buf_valid() when
autocommands were executed.
