Reported by Doug McIlroy, some time ago
(http://lists.gnu.org/r/bug-groff/2011-02/msg00009.html). He discovered it in
1.20.1, but both examples produce essentially the same stderr in 1.23. In his
words:
In groff 1.20.1, -ms input that begins
.KF
.LP
draws a special diagnostic that says .LP "must be in top-level environment,
not `k', when first page is started"
But ... if you put a blank line before .KF,
.KF
.LP
.KE
you get a nonsense diagnostic: "KE without KS or KF".
Both diagnostics strike me as wrong. Why shouldn't a document begin with a
keep?
I met the problem in real life, while debugging pic input. The picture, which
was ultimately to be included in a bigger document via .PS <file, was
accompanied by a caption--thus it was bracketed by .KF/.KE.
