I didn't mean the two commands are completely identical. I meant that
the action of moving out of a string while inside a string is already
achieved by the `up-list' command (which is also generally useful but
has no binding), so changing `forward-sexp' to do that as well would
be redundant. Specially since you'd be removing `forward-sexp's
ability to move inside a string, which is useful.

You seem to think this would make forward-sexp more consistent, but it
would make it less consistent. Currently, a pair of parentheses
delineates a sexp in the same way that a pair of double quotes does.
If you place point at the "a" on the following two examples,
`forward-sexp' will do the exact same thing in both cases. That's

    (abc def)
    "abc def"

If you want to move out of a string, just use the same command you
would use on parentheses (`up-list').
If you want to mark a whole string while inside it, just use the same
procedure you would use on parentheses (`backward-up-list' with
