I think it may be useful, though I've never really needed it.

For me, a better way would be to support Emacs/Vi mode lines. I know
Gedit has a plugin for that, maybe this functionality can be borrowed
from there. Mode lines will be also useful for specifying document
encoding so that user don't have to choose it manually each time it
opens the file (I sometimes have to work with files in cp1251,
traditional codepage for Russian Windows…).
