I'm not sure what you're trying to say here, I know those are the characters
that the current escaping code uses; what I want is for it to _only_ escape
those characters.  So if a filename is `hellow\243\133 world' (pretend those
`\...' sequences are actually chracters), I'll see `hellow\243\133\(sp)world'.

Not if there can be \(U...) escapes -- those are pain to deal with even if
they're only 8 bits.

That was my _whole point_ -- I don't want the possibly open-ended and
certainly annoying (can't parse it with regexp substitution) full escaping
langage, I want the raw filenames with only whitespace escaped (which can be
parsed with only [simple] regexp substitution).

Obviously I realize that I'd be responsible for keeping it up to date, but
then since it would have a fixed set of escapes -- space, backslash, newline
tab -- that would be unlikely to be a problem.

Oh, how nice.
