Re: 3 dots vanish at end of filled line

[Richard M. Stallman]

    If this would be unacceptable, then a less radical departure from the
    current Emacs Info situation would be to recognize titles by the top
    of the node pattern:

How about recognizing them based on the number of characters in each
line?  For a title or heading, you have a certain number of characters
of text, and the following line has the same number of characters, all
the same, and they are one of the fixed set used for "underlining".

If filling leaves an ellipsis on a line by itself, the previous
line will be a lot more than 3 characters long.  So this criterion
will not match.

This criterion should work both for node titles
and for headings in the middle of a node.
