Move the "Specifying Single Revisions" and "Specifying Multiple
Revisions" help topics from the manual page into the helptable
so they are available both online and in the manual page.

    ('revs|revisions|Specifying Single Revisions',
    r'''
    Mercurial accepts several notations for identifying individual
    revisions.

    A plain integer is treated as a revision number. Negative
    integers are treated as offsets from the tip, with -1 denoting the
    tip.

    A 40-digit hexadecimal string is treated as a unique revision
    identifier.

    A hexadecimal string less than 40 characters long is treated as a
    unique revision identifier, and referred to as a short-form
    identifier. A short-form identifier is only valid if it is the
    prefix of one full-length identifier.

    Any other string is treated as a tag name, which is a symbolic
    name associated with a revision identifier. Tag names may not
    contain the ":" character.

    The reserved name "tip" is a special tag that always identifies
    the most recent revision.

    The reserved name "null" indicates the null revision. This is the
    revision of an empty repository, and the parent of revision 0.

    The reserved name "." indicates the working directory parent. If
    no working directory is checked out, it is equivalent to null.
    If an uncommitted merge is in progress, "." is the revision of
    the first parent.

    ('mrevs|multirevs|Specifying Multiple Revisions',
    r'''
    When Mercurial accepts more than one revision, they may be
    specified individually, or provided as a continuous range,
    separated by the ":" character.

    The syntax of range notation is [BEGIN]:[END], where BEGIN and END
    are revision identifiers. Both BEGIN and END are optional. If
    BEGIN is not specified, it defaults to revision number 0. If END
    is not specified, it defaults to the tip. The range ":" thus
    means "all revisions".

    If BEGIN is greater than END, revisions are treated in reverse
    order.

    A range acts as a closed interval. This means that a range of 3:5
    gives 3, 4 and 5. Similarly, a range of 4:2 gives 4, 3, and 2.
