Hmm... the documentation does indeed imply backslash is some sort of a
quote for history.  Actually, I think it's just talking about escaping
the initial ! and then goes into its usual "it sort of vaguely works
like this but nobody ever really thought it through from beginning to
end" mode.  However, you might think you were morally entitled to have a
backslash at that point either isolate the backslashed expression from
what went before (so it behaves just like a single !), or to be treated
as a string argument, and I would think the second, the one you
mentioned, is rather more useful.
