JFTR, that patch was added to man-pages-5.11, the Changes list

| environ.7
|     Bastien Roucariès
|         Reorder the text
|             Move the text describing how to set environment variable before
|             the list(s) of variables in order to improve readability.
|     Bastien Roucariès
|         Document convention of string in environ
|             Document the name=value system and that nul byte is forbidden.
|     Bastien Roucariès
|         Document that HOME, LOGNAME, SHELL, USER are set at login time
|             and point to the su(1) manual page.
|     Bastien Roucariès
|         Add see also ld.so(8) for LD_ variables
|     Michael Kerrisk  [Bastien Roucariès]
|         Improve the description of PATH
|             Add more details of how PATH is used, and mention the legacy
|             use of an empty prefix.
|     Bastien Roucariès  [Alejandro Colomar, Bastien Roucaries, Vincent Lefevre]
|         Document valid values of pathnames for SHELL, PAGER and EDITOR/VISUAL
|     Michael Kerrisk  [Bastien Roucariès]
|         Note the default if PAGER is not defined
|     Michael Kerrisk
|         Be a little more precise when discussing 'exec'
|             Say "execve(2)" instead of "exec(3)", and note that this step
|             starts a new program (not a new process!).
|     Michael Kerrisk  [Bastien Roucariès]
|         Relocate and reword the mention of _GNU_SOURCE

and the man page now reads

| PAGER
|        The user's preferred utility to display text files. Any
|        string acceptable as a command-string operand to the sh -c
|        command shall be valid.  If PAGER is null or is not set, then
|        applications that launch a pager will default to a program such
|        as less(1) or more(1).
|
| EDITOR/VISUAL
|        The user's preferred utility to edit text files.  Any string
|        acceptable as a command_string operand to the sh -c command
|        shall be valid.

So this bug can be closed once that version enters Debian.

Cheers,
Flo
