[PATCH] replay: Fix documentation of the --contained flag

[Gabriel de Perthuis <g2p.code@gmail.com>]

There was a paragraph describing the behaviour of that flag (which
affects branches and refs), but referring to it as --onto.
--contained is used with --onto but it is a more specific flag.
--onto by itself refers to a commit and does not have the described
effect on branches.
