Exception holes, again.

How could I have figured out this by myself? I did a text search for
api_error over my ActivePython distribution, w/o success. Is it burrie din
those pyd-files?

I'm not sure if it's explicitly documented, but one good way is to do
a dir() of the module at hand - you'll find an "error" object in both
pywintypes and the individual modules such as win32api.

It is a bit confusing that the internal class is called api_error (and
that's how the instance objects display themselves) but the actual
instance is called error.  But having an "error" object in a module
for exceptions is reasonably common, so a good thing to check for.
