    ``specs`` can contain integers, in which case they are assumed to be
    revision numbers.

    It is assumed the revsets are already formatted. If you have arguments
    that need to be expanded in the revset, call ``revset.formatspec()``
    and pass the result as an element of ``specs``.

    Specifying a single revset is allowed.

    Returns a ``revset.abstractsmartset`` which is a list-like interface over
    integer revisions.
