The latter are `self-explanatory' only because they're used in C, and so are
very familar to programmers. \s is not.

No, you're missing the point. My object to `?' is that the `?' is not
visually distinct from the `S' -- they tend to `run into' each other.
`\', on the other hand has a bunch of whitespace on the right side of it's
glyph, and so is much more visually distinct from the following character.
So getting rid of the `#' doesn't help at all.
Morever, `#' is _good_ becaues it's the general lisp syntax for special
syntax, so a lisp programmer will be much more likely to realize what's going
on (if he's unfamiliar with this particular bit of syntax) if he sees #\SPC
than if he sees ?SPC.

I don't know, but I think it doesn't matter; we should just use a `#' escape.
