Hmm, yes. I think I was misguided about the proper semantics when I
implemented MANLESS. I've committed this change upstream:
Fri Dec 21 21:29:27 GMT 2012 Colin Watson <cjwat...@debian.org>
* src/man.c (main): Use $MANLESS as the default for prompt_string if
the -r option was not used.
(setenv_less): Remove code to copy $MANLESS verbatim into $LESS.
* man/man1/man.man1 (Controlling formatted output, ENVIRONMENT):
Describe new behaviour of $MANLESS.
* man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update.
This means that the following environment variable setting would work
for you:
MANLESS=' Manual page $MAN_PN ?ltline %lt?L/%L.:byte %bB?s/%s..?e (END):?pB
%pB\%..'
Now, this is at the cost of two incompatibilities. Firstly, anyone who
actually wanted literal "$MAN_PN" in their prompt now has to escape it
(e.g. by interposing some no-op less prompt string fragment such as
"?a."; and with less >= 456 they need an additional backslash before the
$). I'm not so worried about this. Secondly, -r now overrides MANLESS
rather than the other way round; while this is a change, I think it's
definitely more standard and correct.
Thanks,
