Specifying Multiple Revisions

    When Mercurial accepts more than one revision, they may be specified
    individually, or provided as a topologically 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 9:6 gives 9, 8, 7, and 6.
