No option that I know of, but you can partially accomplish this using
autocmds.
Try putting the following in your .vimrc:
augroup AutoDiffUpdate
au!
autocmd InsertLeave * if &diff | diffupdate | let b:old_changedtick
= b:changedtick | endif
autocmd CursorHold *
\ if &diff &&
\ (!exists('b:old_changedtick') || b:old_changedtick !=
b:changedtick) |
\ let b:old_changedtick = b:changedtick | diffupdate |
\ endif
augroup END
This will automatically update the diff whenever you leave insertmode,
or when you haven't moved the cursor for a while and changes have been
made to the buffer since the last time this automatic diffupdate
fired.
I may run with this for a while, though I imagine it might get
annoying because of the auto-diffupdate firing after using commands
like dp and do...maybe I'll add mappings for those commands to update
the old_changedtick as well.
