The file cmbase.mf[1,3] now contains the line
r=charuw.u=round((moduw.tu-2).charuw/uw);

Please try to make cmr10 with this line changed to
r=charuw.u=round((moduw.tu-1).charuw/uw);

They might look a lot nicer! Then again...

The best way to do this safely would be to copy cmbase.mf[1,3] to
whatever area you are running MF from, then make the change; METAFONT
will use the cmbase on your area if it exists.

Thanks for helping in this experiment.
