Yeah, actually that's a pet peeve.
I much prefer a general-purpose text editor to have but a
single escape character (which can escape itself); otherwise
one ends up having to escape normal text characters, *and*
there is no convenient way to expand the editor special-
purpose syntax without breaking existing editing scripts.
Somebody (perhaps me) should write a good paper about
special characters and escape sequences.
