Dear Maintainer,
* What led up to the situation?
Checking for defects with
[test-][g|n]roff -mandoc -t -K utf8 -ww -b -z <man page>
[test-groff is a script in the repository for "groff"]
* What was the outcome of this action?
troff: backtrace: '/home/bg/git/groff/build/s-tmac/an.tmac':562: macro 'B'
troff: backtrace: file '<stdin>':117
troff:<stdin>:117: warning: ignoring escape character before '+'

troff:<stdin>:174: warning: cannot select font 'F'
troff: backtrace: file '<stdin>':534
troff:<stdin>:534: warning: [page 6, 9.1i]: cannot break line
* What outcome did you expect instead?
No output (warnings).

Remarks and a patch are in the attachments.

Versions of packages xserver-common depends on:
ii x11-common 1:7.7+23

-- no debconf information
Any program (person), that produces man pages, should check its content for
defects by using
groff -mandoc -t -ww -b -z [ -K utf8 | k ] <man page>
The same goes for man pages that are used as an input.
For a style guide use
mandoc -T lint
-.-
So any generator should check its products with the above mentioned
'groff' and additionally with 'nroff ...'.
This is just a simple quality control measure.
The generator may have to be corrected to get a better man page,
the source file may, and any additional file may.
-.-
The difference between the formatted outputs can be seen with:
nroff -man <file1> > <out1>
nroff -man <file2> > <out2>
diff -u <out1> <out2>
and for groff, using
"printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -man -Z - "
instead of "nroff -man"
Add the option "-t", if the file contains a table.
Read the output of "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 -z"
export MAN_KEEP_STDERR=yes (or any non-empty value)

Change (or include a "FIXME" paragraph about) misused SI (metric)

Mark a full stop (.) and the exclamation mark (!) with "\&",
if it does not mean an end of a sentence.
This is a preventive action,
the paragraph could be reshaped, e.g., after changes.
When typing, one does not always notice when the line wraps after the
period.
There are too many examples of input lines in manual pages,
that end with an abbreviation point.
This marking is robust, and independent of the position on the line.

or is in the NAME section (man-pages(7)).
N.B. - (0x2D), processed as a UTF-8 file, is changed to a hyphen

-.-.
Wrong distance between sentences.
Separate the sentences and subordinate clauses; each begins on a new
line. See man-pages(7) ("Conventions for source file layout") and
"info groff" ("Input Conventions").
The best procedure is to always start a new sentence on a new line,
at least, if you are typing on a computer.
Remember coding: Only one command ("sentence") on each (logical) line.
E-mail: Easier to quote exactly the relevant lines.
Generally: Easier to edit the sentence.
Patches: Less unaffected text.
Search for two adjacent words is easier, when they belong to the same line,
and the same phrase.
The amount of space between sentences in the output can then be
controlled with the ".ss" request.
N.B
The number of lines affected can be too large to be in the patch.
