[issue2541] pager redirects error messages to stdout and always sets exit code 0

[Thomas Arendsen Hein]

New submission from Thomas Arendsen Hein <thomas at intevation.de>:

Mercurial 1.7.2 (and 1.6 and default):

$ hg --config extensions.pager= cat foobarbaz
yields exit code 0 and appending 2>foo would not write the error message
to file foo

$ hg --config extensions.pager=\! cat foobarbaz
(or just "hg cat foobarbaz" if no pager configured)
does not have above problems.

What should be done here?
Should the pager be used if there is an error?
