The vertical bars are not escaped, and the scope of the
Cm macro automatically resumes after them,
without repeating the macro. The keywords are ordered alphabetically.
Note that there is a slight ambiguity: When providing the
peers keyword, the above synopsis line
doesn't make it completely clear that the
-s option is still required; that synopsis
line could be misunderstood in the sense that
ntpctl
peers were valid syntax and the
-s option only belonged to
all.
The
mdoc(7)
language doesn't allow to resolve such ambiguities in the SYNOPSIS; doing so
is the job of the DESCRIPTION section.
It would be acceptable to provide a visual cue by suppressing spacing:
ntpctl
-s
all|peers|Sensors|status
Or equivalently:
ntpctl
-s
all|peers|Sensors|status
However, in such a simple case, this is not required.
