Fix some bugs in #'substitute, #'nsubstitute. src/ChangeLog addition: 2015-03-04 Aidan Kehoe <kehoea@parhasard.net> * sequence.c (count_with_tail): Accept COUNT from #'substitute, #'nsubstitute too. * sequence.c (FdeleteX): Only remove COUNT from the arguments if FROM-END is non-nil. * sequence.c (Fnsubstitute): Remove COUNT from the arguments if specified and FROM-END is non-nil. * sequence.c (Fsubstitute): Remove COUNT from the arguments if specified and FROM-END is non-nil. Do this before calling count_with_tail(). When we encounter the cons return by count_with_tail(), use the replacement object. tests/ChangeLog addition: 2015-03-04 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Add some tests for #'substitute.
