It usually contains a break-down of the options (if documenting a

command).

.It Em CONTEXT

This section lists the contexts in which functions can be called in section 9.

The contexts are autoconf, process, or interrupt.

Implementation-specific notes should be kept here.

This is useful when implementing standard functions that may have side

Line 889 to close out a literal context opened with

.Sx \&nf .

This behaviour may not be portable.

.It

In quoted literals, GNU troff allowed pair-wise double-quotes to produce

a standalone double-quote in formatted output.

It is not known whether this behaviour is exhibited by other formatters.

.It

troff suppresses a newline before

.Sq \(aq

macro output; in mandoc, it is an alias for the standard

.Sq \&.

control character.

.It

The

.Sq \ef

scaling unit is accepted by mandoc, but rendered as the default unit.

.It

The

.Sx \&sp

macro does not accept negative values in mandoc.

In GNU troff, this would result in strange behaviour.

In page header lines, GNU troff versions up to and including 1.21
