I'd like both sections to be identical in the following page (with the
behavior of the first one).


$ cat RS.man 
.TH RS 7 to-morrow Alex
.SH Continuing TP with IP
.TP
tag
First paragraph.
.IP
Second paragraph.
.SH Continuing TP with RS
.TP
tag
.RS
First paragraph.
.PP
Second paragraph.
.RE


$ MANWIDTH=72 man ./RS.man | cat
RS(7)              Miscellaneous Information Manual              RS(7)

Continuing TP with IP
     tag    First paragraph.

            Second paragraph.

Continuing TP with RS
     tag
            First paragraph.

            Second paragraph.

Heh, I've managed to reproduce it!  It seems I run that thing just
before installing groff from git in this computer:

$ /usr/bin/groff --version | head -n1
GNU groff version 1.23.0
$ /usr/local/bin/groff --version | head -n1
GNU groff version 1.23.0.497-e982
$ MANROFFOPT=--version man man | head -n1
GNU nroff (groff) version 1.23.0.497-e982
$ PATH=/usr/bin
$ MANROFFOPT=--version man man | head -n1
GNU nroff (groff) version 1.23.0
$ MANWIDTH=80 man groff_man_style | wc
   1439    9943   81331

I've taken an entire year to read the Picture of Dorian Gray, if that
gives you an idea.  :D

Cheers,
