Before this goes any further:

* I know that ExitProcess() also works for GUI apps, but I have no
intention to hack MFC just to properly return such a value (yes, I'd
have to hack MFC here or create some other very ugly hack, since TSVN is
dialog based, and a dialog must return FALSE so the message queue can
stop and the application exit).
* I also know that there is a way to get a console back, but that never
works fully (tried that with SubWCRev once: worked for the default
windows console, but no other console or some other scripting engines):
now there are two SubWCRev exes

TSVN is a GUI app and not intended for scripting. The CL client should
be used for that: use the right tool for the right job.
