I think explicitly giving the name of the obsolete command

and the replacement command would be better. Something similar
to the format used by `define-obsolete-function-alias'

    `split-window' is an obsolete command (as of 24.4); use 
`split-window-below' instead


or maybe

    The command `split-window' is obsolete (as of 24.4); use 
`split-window-below' instead

Encountering obsolete commands should be pretty rare,

so I think a detailed message is more important than
the convenience aspect.

Perhaps something like `disable-command' could be used
instead of just a message.
