Correct, I did not even run "make install".

I was not able to reproduce the bug then; but even with the file back in
place I couldn't, although it happened both in my regular session and
the "emacs -Q" instance I started specially for reporting it.  Now it
does not happen in either. :-/

There's another problem in that the file is not truncated to
gamegrid-score-file-length lines, but that has been the case for a long
time IIRC.

Cheers,
