groff Bug Report
GROFF VERSION: 1.23.0
I can test it against git HEAD if anyone tells me how to compile it
without texinfo.
PLATFORM:
Linux 6.3.13_2 #1 SMP PREEMPT_DYNAMIC Sun Oct 1 20:21:07 UTC 2023 x86_64
GNU/Linux
CONFIGURATION REPORT:
I doubt the output of my distro's package manager would be very
helpful as it doesn't mention the parameters used to build it.
The only useful thing it mentions is:
source-revisions: groff:20c6682913
Here is the distro's build system's current template for groff:
# Template file for 'groff'
pkgname=groff
version=1.23.0
revision=1
build_style=gnu-configure
configure_args="--without-x --disable-rpath"
hostmakedepends="perl bison ghostscript"
makedepends="zlib-devel"

fi
post_install() {
# From Arch:

# The output chars don't match keyboard chars...
for f in man mdoc; do
cat ${FILESDIR}/site.tmac >> \
${DESTDIR}/usr/share/groff/site-tmac/${f}.local
done
}
INPUT FILES: ne.tr
COMMAND LINE: groff -b -ww -Tpdf -P-pa5 ne.tr > ne.pdf
DESCRIPTION OF INCORRECT BEHAVIOUR:
.bp causes line break before breaking a page, while .ne doesn't.
This behavior can be observed in the PDF output at the end of
pages 1 and 2. I have turned off hyphenating at the end of the
page, so the fact there is hyphenation there also clearly shows
something is wrong.
You can compare .ne's behavior against .bp by replacing the marked
.p macro calls with calls to the .BP macro.
SUGGESTED FIX: Ensure .ne breaks line before breaking the page.
