Re: Patch: Syntax and Hard Newlines

[Richard Stallman]

It seems to be a 1% slowdown, which is small enough we
can ignore it.

The only way we can get more thorough testing is to make the change
(enabling parse-sexp-lookup-properties by default) and have people try
it for a while.  If we don't NEED to do that now, let's not.
However, if there is a bug which is hard to fix in any other way,
we can fix it this way now.
