Thanks for the suggestion. I've implemented this upstream, though I made
sure to preserve the warnings when output is not being directed to a
pager in order to retain their usefulness to tools such as lintian that
call man noninteractively.

Discard stderr from formatting processes when outputting to a pager,
to avoid visual corruption from any error messages (thanks, Vincent
Lefevre; Debian bug #372939).
* lib/pipeline.h (struct command): Add discard_err member.
* lib/pipeline.c (command_new, command_dup): Initialise discard_err.
(pipeline_start): Redirect the child's stderr to /dev/null if
discard_err is set.
* src/man.c (discard_stderr): New function to set discard_err on all
commands in a pipeline.
(format_display_and_save, format_display): Use it on format_cmd.
* docs/NEWS: Document this.
Cheers,
