Details:

I don't like having the line length of the footnotes only 5/6 the
width of the columns: I like them to be the full width of the current
line, whether that is in one column mode or multicolumn mode.  I'd
like to be able to change that default, to avoid having to change the
footnote line length in multicolumn mode using the undocumented
fn:MCLL.

I propose adding a string variable, FR (footnote ratio), that defaults
to to 5/6 for compatibility and replaces the uses of the literal 5/6
for setting footnote line length.  You can set this at the beginning
of your document, or before each .MC or .2C.  For my use I'd always
set it to 1, making the footnote line length the same as the line
length.

(I think making setting FR effective before the next footnote, like
setting FL in one column mode, would take rewriting par@reset to
recalculate fn:MCLL every time, instead of just after a .MC.)

I've included a patch that makes the necessary changes in groff.texi,
groff_ms.7.man, and s.tmac.
