Use the pager given by the environment to display long output

Unix systems usually have a PAGER environment variable set.
If it is set, mercurial will use the pager application to display
output.

Two configuration variables are available to influence the
behaviour of the pager:
  pager.application
    sets the application to be used
  pager.quiet
   silences Broken Pipe errors that might occur when the user
   quits the pager before mercurial finished to write the output
