patchbomb: use modern pager to display -n/--test result (BC)

This should provide more consistent UX, but is a BC because the pager will
no longer be fired up for each message.

    node as nodemod,

    files.

    With -n/--test, all steps will run, but mail will not be sent.
    You will be prompted for an email recipient address, a subject and
    an introductory message describing the patches of your patchbomb.
    Then when all is done, patchbomb messages are displayed. If the
    PAGER environment variable is set, your pager will be fired up once
    for each patchbomb message, so you can verify everything is alright.

    In case email sending fails, you will find a backup of your series
    introductory message in ``.hg/last-email.txt``.

    The default behavior of this command can be customized through

        if replyto:
            m['Reply-To'] = ', '.join(replyto)
        if opts.get('test'):
