This one's easy.  Execute emulate BEFORE setting localoptions.  The
setting of localoptions at the *end* of the function is what determines
which options are restored.

I hadn't considered that use of emulation before.  Do you think maybe
the emulation mode should be restored by localoptions in the way
options are?  Even after my patches, the emulation does have some
direct effect -- the single-letter option names.  I don't think that
should be changed.
