Ah yes correct, I forgot this one. The new changeset 8ace059cdffd removes it.
It is not perfect, there is still a race condition in
looks_like_python() (pysource.py) if KeyboardInterrupt occurs between
the file is opened and the beginning of the "with infile" block, but
it don't think that it is really important ;-)
