Yes, this looks good to me.  It could go in as-is, but see my question
below...

Hmm, we output octal sequences without a backslash; should the info page
be any more verbose that it is one of: a single-byte printable
character, a C backslash escape, or an octal sequence?  Or does that
just clutter things (seeing three octal digits, even without a
backslash, still makes it easy to determine that it can be used as an
escape sequence).

For the --help output, terse is good, so I don't see any improvements to
your change here.
