   Since the command defined by PAGER (or MANPAGER) is feeded the data by
   standard input it does not work to do:

      setenv PAGER 'wsc -c more'

   However, it is possible to do:

      setenv PAGER 'cat > /tmp/.m; wsh -c more /tmp/.m'

   It is probably a good idea to add the option -H to the invocation of
   wsh. Personally I would use winterm instead of wsh, as the look and
   feel of winterm is defined by the environmental variable WINTERM.
