Not really a standard, but man page for man on my OSX laptop says:

"""
       -P  pager
              Specify which pager to use.  This option overrides the
MANPAGER environment variable, which in turn overrides the PAGER
variable.
"""

POSIX only mandates PAGER.  See
<http://pubs.opengroup.org/onlinepubs/007908799/xcu/man.html>.

As I said before, since pydoc is not man, if we want a pydoc-specific
variable to override PAGER, it should be callled PYDOCPAGER.
