Summary 0000956: Documentation unification regarding PAGER
Description The problem i see with the current occurrences is that for PAGER itself -- and only there -- the standard states (p. 2911, l. 96088) that

  When standard output is a terminal device,

effectively restricting PAGER to this specific mode, whereas otherwise it says "shall be paged through the command specified by the PAGER environment variable" which is a completely different thing given that PAGER can be set to "Any string acceptable as a command_string operand to the sh -c command".
(Especially if an implementation allows special values like "0" to mean "always use PAGER", which would be a standard-extension, though.)

FreeBSD etc. Mail implementations act accordingly to an updated Issue, NetBSD Mail seems to use the PAGER regardless. (My own clone will act like the former from version 14.8.1, i.e., tomorrow, on.)
Desired Action Change, in the range 96322-96324

  crt=number Pipe messages having more than number lines through the command specified by the value of the PAGER variable. The default shall be nocrt. If it is set to null, the value used is implementation-defined.

to

  crt=number Paginate messages having more than number lines as described for the PAGER variable. The default shall be nocrt. If it is set to null, the value used is implementation-defined.

In the line ranges 96592-96594 and 96598-96600, change

  If crt is set, the messages longer than the number of lines specified by the crt variable shall be paged through the command specified by the PAGER environment variable.

to

  If the message is longer than crt lines ([REF]), the output shall be paginated as described for the PAGER variable.

 I said, rather context-free,

  allows special values like "0" to mean "always use PAGER"

and that referred to the internal variable *crt*.

 Interpretation response
------------------------
The standard is unclear on this issue, and no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor.

Rationale:
-------------
The standard is ambiguous if the standard output is not a terminal.

Notes to the Editor (not part of this interpretation):
-------------------------------------------------------
At page 2911 line 96088-96090 change
When standard output is a terminal device, the message output shall be piped through the command if the mailx internal variable crt is set to a value less the number of lines in the message; see Internal Variables in mailx (on page 2915).
to
When standard output is a terminal device, the message output shall be piped through the command if the mailx internal variable crt is set to a value less than the total number of lines in the messages; see Internal Variables in mailx (on page 2915). When standard output is not a terminal device, it is unspecified whether the message output is written directly to standard output or is subject to pagination.

On P2915, L96288 change:
no name
to:
noname
(i.e. remove the space)

At page 2916 lines 96322-96324, change:
crt=number Pipe messages having more than number lines through the command specified by the value of the PAGER variable. The default shall be nocrt. If it is set to null, the value used is implementation-defined.
to
crt=number Paginate message output as described for the PAGER variable. The default shall be nocrt, disabling this pagination. If it is set to null, the value used is implementation-defined.

At page 2923 lines 96592-96594 and 96598-96600, change:
If crt is set, the messages longer than the number of lines specified by the crt variable shall be paged through the command specified by the PAGER environment variable.
to
If crt is set, the output shall be paginated as described for the PAGER variable.

 Re: Note: 0002703
The resolution of Note: 0003094 includes that use case implicitly for terminal devices, by clarifying the expectation of nocrt. For non-terminal devices it would still be an extension.
