I completely agree.  Someone deleted the code for other styles to fix a
bug, instead of fixing the real cause of that problem, which I did on
master.

It's too late to change this inside the pretests, but it should work on
master.  As a bonus, you get the ability to change the input style, and
use any input method supported by GTK+.  To switch back to
`overthespot', simply add the following to your .Xresources file and
apply it:

  Emacs.inputStyle: overthespot

Also, please report any bugs you find with the new input style options.

XIM is a legacy interface, and at support for it has in general
experienced quite some bit-rot.

Closing, since it's been fixed on master.
