Dear Maintainer,
here are some notes and editorial fixes for the manual.
The patch is in the attachment.
-.-
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 two HYPHEN-MINUSES (code 0x2D) to an em-dash (\(em),
if one is intended. 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 "-" (end of options) then use "\-\-".

-.-.
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.

Split lines longer than 80 characters into two or more lines.
Appropriate break points are the end of a sentence and a subordinate
clause; after punctuation marks.
