keyboard handling (specifically mutt_getch)

[Allister MacLeod <amacleod@xxxxxxxx>]

I'm trying to figure out the normal flow of the km_dokey() function in
mutt, and was curious about the line (around 390 of keymap.c):

    /* do we have an op already? */
    if (tmp.op)
    {
    ...

As far as I can tell, tmp is only ever set by assignment from the
mutt_getch() function.  Upon reading that function, it looks like
maybe the .op field of the return value is only ever set when there is
an error (and then its value is OP_NULL).  I'm not sure, though.  Can
anyone tell me whether there are other cases where tmp.op would be
nonzero?

Thanks,
 Allister
