[Pkg-gmagick-im-team] Bug#1099631: display-im7.q16.1: Some remarks and a patch with editorial changes for this man page

Package: imagemagick-7.q16
Version: 8:7.1.1.43+dfsg1-1
Severity: minor
Tags: patch
* 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>:13: style: 2 leading space(s) on input line
[...]
troff:<stdin>:127: warning: trailing space in the line
[...]
* What outcome did you expect instead?
No output (no warnings).

Reduce space between words.

Remove space in the first column, if not indented.
Use ".in +<number>n" and ".in" to end it; ".nf" and ".fi" to end
it, for an extra indention.
This i changed into tables.

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.

-.-.
Add a "\&" (or a comma (Oxford comma)) after "e.g." and "i.e.",
or use English words
(man-pages(7)).
Abbreviation points should be marked as such and protected against being
interpreted as an end of sentence, if they are not, and that independent
of the current place on the line.
125:By default, the image format of `file' is determined by its magic number. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output.
-.-.
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 "\&".
Some sentences (etc.) do not begin on a new line.
Split (sometimes) lines after a punctuation mark; before a conjunction.
Lines with only one (or two) space(s) between sentences could be split,
so latter sentences begin on a new line.
Use
#!/usr/bin/sh
sed -e '/^\./n' \
-e 's/\([[:alpha:]]\)\. */\1.\n/g' $1
to split lines after a sentence period.
Check result with the difference between the formatted outputs.

-By default, the image format of `file' is determined by its magic number. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output.

-------------- next part --------------
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.
"git" has a "tool" to point out whitespace,
see for example "git-apply(1)" and git-config(1)")
Not beginning each input sentence on a new line.
Line length and patch size 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 -d -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 -d -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)
