New Revision: 295032
URL: https://svnweb.freebsd.org/changeset/base/295032

Log:
  Use '^[>+][^+]' instead of '^[>+]' with grep(1) when filtering the
  diff(1) output between two files in "new_only"-mode. Otherwise,
  with the default of using unified format a remnant of the header
  in the output is the result. This is especially irritating when
  the two files differ but the second one is empty, amounting to the
  vestige of the header being the only readout.
