I'll give you another ah-hah moment: that is exactly the list of all the
non-letter non-digit ASCII characters.  (In order, even.)  So this seems
to boil down to "if (ispunct(ch)) add backslash".

Ick.

Perhaps so, especially in view of all the encoding dependencies that
would arise if we tried to fix that.  Still, I'm getting a stronger and
stronger impression that ReST is a good standard to stay away from.
Somewhere along the line its designers lost track of the notions of
simplicity and predictability.  It's probably peachy for hand-generated
text, but for machine-generated output there are way too many cute special
cases.
