Details:

Internally, groff's s.tmac defines a macro called "FP", and uses it to control
the printing of footnotes.  At the point of definition, I see:


.\" This can be redefined. It gets a second argument of 'no' if the
.\" first argument was supplied by the user, rather than automatically.
.de FP
...


To me, this suggests that the intention is to provide a hook, (albeit
inconsistent with other ms implementations — e.g. Plan-9's ms manpage
documents an FP macro associated with font positions), whereby the user may
choose to modify the appearance of footnotes, yet the documentation (neither
manpage, nor info) has absolutely no mention of it.
