fix regex typos in new "Accept" test for Bison

[Paul Eggert]

I installed this.  The old regular expression was clearly bogus, but
the sed command just happened to work anyway -- except that it ran
into a bug on Solaris 10 sed, which doesn't work with weird
expressions like that.  A comedy of errors.
