Actually, we should have completion for input methods.  It would be handy
for things like the TeX input method.  Currently if I hit TAB after \a
I do get some sort of "list of possible completions", but it's displayed
as a tree which is kind of hard to read and I can select one of them
from the list.  Also TAB after \rig doesn't complete to \right as normal
completion would.

I don't forsee any serious problem, except when when displaying the
complete list of completions (e.g. if you hit TAB before entering
any input).
