Patch: FYI: natIconv -vs- EINVAL/E2BIG

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in on the trunk.

This fixes a bug in natIconv.cc when conversion returns EINVAL or
E2BIG.  The original reporter never got back to me about this fix, but
I think it is right and I've been running it for a while without harm.
