Use new language features in #'call-process-internal now they're available. lisp/ChangeLog addition: 2013-06-17 Aidan Kehoe <kehoea@parhasard.net> * process.el (process-synchronize-point): Moved to a label. * process.el (call-process-internal): Now we have better language features, use them rather than creating a closure ourselves or exposing a utility function when there is no need for that with a well-implemented labels function.
