Re: bad page breaks and ugly formatting

[Karl Berry]

      . Compute the height and depth of the @group's vbox.

      . If it doesn't fit on the current page, and if the distance from
        the current position (before the vbox) to the bottom of the page
        is larger than \vfilllimit times the page length, insert \vfill
        before emitting @group's vbox.

I installed this patch, more or less.  I left out the \setvfilllimit
thing, since I didn't really want to introduce a new command just for
this.  It's just as easy to do
@tex
\gdef\vfilllimit{0.6}
@end tex

The new texinfo.tex is on prep and in cvs.  Includes today's other
changes, too.

Let me know if problems.  I'll test it out more after you send me the
current groff.texinfo :).

Thanks!
