Content:
* Document that the command has a default file list.
* Demote "COMMANDS" section to "Operations" subsection. The former term
is (1) too easily confused with Unix commands and (2) not a widely
used section heading in man pages.
Style:
* Italicize command names.
* Italicize file names.
* Use idiomatic man page cross references.
* Present operation and option letters in alphabetical order.
* Render option descriptions as full sentences.
* Set bug list as a bulleted list.
Markup:
* Break input lines at sentence boundaries.
* Favor use of man(7) font selection and alternation macros over roff(7)
font selection escape sequences.
* Drop numerous extraneous paragraphing macro calls. See subsection
"Horizontal and vertical spacing" of groff_man(7).
* Replace use of *roff requests to break lines and vertically space with
calls of paragraphing macros, which is what they're for. Two things
the page author didn't know: `.sp 1` already implies a break, so the
preceding `.br` was redundant. `.sp 1` without an argument already
means to vertically space by 1 vee; that is, the "1" argument was
superfluous. It was a bad idea anyway because the default
inter-paragraph spacing in man(7) is not one vee, but 0.4v--this
matters when typesetting. It has also been the case since 1979.
* Use `RS` and `RE` macros instead of a literal tab to achieve a
relative inset. Use of the macros is more idiomatic.
* Use `EX` and `EE` to attempt to set the examples in a monospaced font
family. These are extensions and are silently ignored by formatters
that don't support them.
groff_man(7):
.EX
.EE Begin and end example. After .EX, filling is disabled and a
constant‐width (monospaced) font is selected. Calling .EE
enables filling and restores the previous font.
.EX and .EE are extensions introduced in Ninth Edition Unix.
Documenter’s Workbench, Heirloom Doctools, and Plan 9
troffs, and mandoc (since 1.12.2) also support them.
Solaris troff does not. See subsection “Use of extensions”
in groff_man_style(7).
* Kill off useless trailing space on input line.
