No.

First the particular failiure here is that do_local_ini can't find any ini
to parse. BUT do_local_ini will not be called unless do_fromcwd determines
that a setup.ini exists.

This is just as well, since currently if IDD_S_LOAD_INI does got posted back
to threebar.cc, setup hangs on the progress page, since do_fromcwd does not
do what the code in threebar.cc seems to believe it does.

So, I'm adding an exit in a very narrow edge case (and the exit is
implicitly a "FIXME: Use an Exception").

Max.
