Are you actually trying to exit from the main shell here?  It claims to
be a hook into accept-line but it doesn't look to me like it is.

The key here is presumably sorting out what functions are running at
what level, i.e. where the "exit" command is first run and where the
shell actually exits (you could trying adding a message after "exit" to
see if that gets run, though that probably won't help since "retflag" is
likely to be set at that point).  In particular, what should happen is
the code at the end of doshfunc() causes the shell to exit at the end of
_accept_and_quit.  The simpler the case, the more likely
the relationship is to come out.
