Apply ellipsis advice from groff_man_style(7).
• The dummy character escape sequence \& follows the ellipsis when
further text will follow after space on the output line, keeping
its last period from being interpreted as the end of a sentence
and causing additional inter‐sentence space to be placed after
it. See subsection “Portability” below.
[...]
\& Dummy character. Insert at the beginning of an input
line to prevent a dot or apostrophe from being
interpreted as beginning a roff control line. Append to
an end‐of‐sentence punctuation sequence to keep it from
being recognized as such.
\| Thin space (one‐sixth em on typesetters, zero‐width on
terminals); a non‐breaking space. Used primarily in
ellipses (“.\|.\|.”) to space the dots more pleasantly on
typesetters like dvi, pdf, and ps.
Break some long input lines.
\newline Join the next input line to the current one. Except for
the update of the input line counter (used for diagnostic
messages and related purposes), a series of lines ending
in backslash‐newline appears to groff as a single input
line. Use this escape sequence to split excessively long
input lines for document maintenance.
Set the ellipsis in roman instead of bold in the few cases where it
wasn't already. As far as I can tell, it is never employed as a literal
in this man page.
Set some Bash literal syntax in bold, not roman, namely command
"$(( ))" and arithmetic "(( ))" substitutions.
Use \(dq special character escape sequence to smuggle a double quote
into paragraph tags that call macros. (All the *roffs I have ready
access to [groff, Heirloom Doctools, DWB 3.3], plus mandoc(1) support
this special character, but Seventh Edition Unix troff does not, and a
grep of Solaris 10 troff suggests it doesn't either. This man page
already uses `aq`, which is no _more_ portable than `dq`--DWB 3.3
supports `aq` on _fewer_ output devices, in fact.)
