That commit did not make the corresponding change to printing, thus breaking the (eq (read (prin1-to-string SYM)) SYM) invariant for those symbols. It's too late in the release cycle to change printing behavior, therefore revert the reader change. Don't merge to master, the print function will be updated there (see "Fix round tripping of read->print for symbols with strange quotes").
