I recently discovered that the FileType autocmd can fire in the middle of the 
sequence of BufRead autocmds if you have several BufRead/BufNewFile autocmds 
like:
  autocmd BufRead *.foo setfiletype foo
  autocmd BufRead *.foo set shiftwidth=8

  autocmd FileType foo set shiftwidth=4

This can cause unpredictable behavior. It can especially be a problem because 
cycling filetype off/on will wipe and redefine the filetypedetect autocmds, 
changing the sequence and reversing the behavior (in this case, causing sw=4 to 
win instead of sw=8).

It seems natural to expect the FileType autocmds to fire after all BufRead and 
BufNewFile autocmds have finished, but lots of people have found by 
trial-and-error that they can access &filetype from BufRead autocmds, so 
there's a lot of vimscript copypasta around that breaks if you reorder Buf 
autocmds.

Would it be reasonable to change vim so that FileType autocmds don't fire 
mid-BufRead or mid-BufNewFile?
