* What led up to the situation?
Checking for defects with a new version
test-[g|n]roff -mandoc -t -K utf8 -rF0 -rHY=0 -rCHECKSTYLE=10 -ww -z < "man
page"
[Use "groff -e ' $' -e '\\~$' <file>" to find obvious trailing spaces.]
["test-groff" is a script in the repository for "groff"; is not shipped]
(local copy and "troff" slightly changed by me).
[The fate of "test-nroff" was decided in groff bug #55941.]
* What was the outcome of this action?
an.tmac:<stdin>:4: style: .TH missing fourth argument; consider package/project
name and version (e.g., "groff 1.23.0")
troff:<stdin>:31: warning: trailing space in the line
troff:<stdin>:59: warning: trailing space in the line
an.tmac:<stdin>:74: misuse, warning: .BR is for at least 2 arguments, got 1
Use macro '.B' for one argument or split argument.
* What outcome did you expect instead?
No output (no warnings).

Any program (person), that produces man pages, should check the output
for defects by using (both groff and nroff)
[gn]roff -mandoc -t -ww -b -z -K utf8 <man page>
The same goes for man pages that are used as an input.
For a style guide use
mandoc -T lint
-.-
Any "autogenerator" should check its products with the above mentioned
'groff', 'mandoc', and additionally with 'nroff ...'.
It should also check its input files for too long (> 80) lines.
This is just a simple quality control measure.
The "autogenerator" may have to be corrected to get a better man page,
the source file may, and any additional file may.
Common defects:
Not removing trailing spaces (in in- and output).
The reason for these trailing spaces should be found and eliminated.
Not beginning each input sentence on a new line.
Line length should thus be reduced.
The script "reportbug" uses 'quoted-printable' encoding when a line is
longer than 1024 characters in an 'ascii' file.
See man-pages(7), item "semantic newline".
-.-
The difference between the formatted output of the original and patched file
can be seen with:
nroff -mandoc <file1> > <out1>
nroff -mandoc <file2> > <out2>
diff -u <out1> <out2>
and for groff, using
\"printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -mandoc -Z - \"
instead of 'nroff -mandoc'
Add the option '-t', if the file contains a table.
Read the output from 'diff -u ...' with 'less -R' or similar.
-.-.
If 'man' (man-db) is used to check the manual for warnings,
the following must be set:
The option \"-warnings=w\"
The environmental variable:
export MAN_KEEP_STDERR=yes (or any non-empty value)
or
(produce only warnings):
export MANROFFOPT=\"-ww -b -z\"
export MAN_KEEP_STDERR=yes (or any non-empty value)
