I do, yes. :-)

Indeed. The whole point is that if the syntax scanning starts outside
the one-line string, the newline acts as a terminator. If it starts
inside the string, the newline doesn't act as anything special.
The complications would come with things like scan-sexps, which when
starting after a newline and scanning backward, would have to check for a
one-line " in the line. I don't see such complications as being
unmanageable.
