* 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 ' $' <file>" to find 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?
troff:<stdin>:36: warning: trailing space in the line
an.tmac:<stdin>:41: misuse, warning: .IR is for at least 2 arguments, got 1
Use macro '.I' for one argument or split argument.
* What outcome did you expect instead?
No output (no warnings).

Input file is setfattr.1
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
-.-
So any 'generator' should check its products with the above mentioned
'groff', 'mandoc', 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.
Common defects:
Input text line longer than 80 bytes.
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.
Lines should thus be shorter.
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 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 -b -z"
export MAN_KEEP_STDERR=yes (or any non-empty value)
-.-.

-.-
Remove space characters (whitespace) at the end of lines.
Use "git apply ... --whitespace=fix" to fix extra space issues, or use
global configuration "core.whitespace".
Number of lines affected is
1
-.-.
Change two HYPHEN-MINUSES (code 0x2D) to an em-dash (\(em),
if one is intended.
" \(em " creates a too big gap in the text (in "troff").
An en-dash is usually surrounded by a space,
while an em-dash is used without spaces.
"man" (1 byte characters in input) transforms an en-dash (\(en) to one
HYPHEN-MINUS,
and an em-dash to two HYPHEN-MINUSES without considering the space
around it.
If "--" are two single "-"
(begin of an option or end of options)
then use "\-\-".

Change -- in x--y to \(em (em-dash), or, if an
option, to \-\-

Use the correct macro for the font change of a single argument or
split the argument into two.

Change a HYPHEN-MINUS (code 0x2D) to a minus(-dash) (\-),
if it
is in front of a name for an option,
is a symbol for standard input,
is a single character used to indicate an option,
or is in the NAME section (man-pages(7)).
N.B. - (0x2D), processed as a UTF-8 file, is changed to a hyphen
(0x2010, groff \[u2010] or \[hy]) in the output.

107:.B "# setfattr -n trusted.md5sum -v d41d8cd98f00b204e00998ecf8427e file.txt
-.-.
Wrong distance between sentences in the input file.
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.
Mark a final abbreviation point as such by suffixing it with "\&".
