    When forward-line errs, it's too late, because the cache is already
    corrupted.

The point is, this is how I know the problem is in the newline cache.
A year ago I debugged the subroutines of Fforward_line and verified
that the problem happened in the call to the newline cache code.

    The cache code is in region-cache.c.

I don't have time to study and debug that.
