B.T.,
I just ran a quick fill paragraph test using text rather than numbers and
what I see is that doing fill-paragraph with a large fill-column setting
does in fact put spaces where the ^js were. (I am running Emacs 21.3 on
XP). In fact this is what I would expect fill-paragraph to do because
usually paragraphs are an series of words separated by spaces and line
feeds rather than a string of numbers separated by line feeds. For
example if I had following two lines:
You should have a go
at it.
I would expect then to be filled as:
You should have a go at it.
not as:
You should have a goat it.
Granted there may be times when even with text is would be preferable to
not have a space replace the line feed, such as:
He went that-a-
way.
should be filled as:
He went that-a-way.
not as:
He went that-a- way.
but they are rare and fill-paragraph is not that smart.

Duh! I was so focused on getting a quick and dirty answer to the number of
digits in Number-of-beast! that the obvious escaped me. I am glad that
fill-paragraph is at least smarter than I am in that it knows enough to
end a "word" after 80 or 100 contiguous characters.
Thanks,
