I'm not very familiar with that code, but from my reading of it, none of
that has been done at this point.
I call Fformat_mode_line (format, Qnil, Qnil, Qnil); instead of
display_mode_element. Fformat_mode_line sets
mode_line_target = MODE_LINE_STRING;
or the like, and then calls display_mode_element, which then won't call
display_string at all, but just put all the computed elements in a list.
So nothing is displayed until that call to display_string, in my reading
of the code.
OK, I've now done some more testing -- I removed my call to
display_string, and no mode line is displayed at all, which kinda
supports my reading of the code?
