Avoid the trailing ";" after the last parallel gap move. Instead, make the
semicolon part of the delimiter between moves.

Before:
gap ([stack:8|w32] = [constant:0];) ([edi|R|w32] = [constant:7]; [edx|R|w32] = [constant:8];)
After:
gap ([stack:8|w32] = [constant:0]) ([edi|R|w32] = [constant:7]; [edx|R|w32] = [constant:8])
