rc3: groff man pages truncated

[Alexis]

Hi all,

i've just installed rc3 via the relevant Gentoo ebuild. My Gentoo 
system is mandoc-based, via the `system-man` USE flag.

Running `man` - actually the `mandoc` binary - still works fine 
overall, but not with the new groff man pages. For example, `man 
groff_man_style` produces this as the entirety of its output:

--- ✂ ---
groff_man_style(7)     Miscellaneous Information Manual 
groff_man_style(7)

Name
      groff_man_style - GNU roff man page tutorial and style 
      guide

groff 1.23.0.rc3               21 February 2023 
groff_man_style(7)
--- ✂ ---

Running `mandoc -man -Tutf8 /usr/share/man/man7/groff_man_style.7` 
produces the same result.

On the other hand, `groff -man -Tutf8 
/usr/share/man/man7/groff_man_style.7` works just fine.

Is there something in 1.23 that mandoc needs to be updated to 
support? Or, more likely, am i just doing something wrong, or not 
doing something right?


Alexis.
