py3: do not pass a memoryview to bdiff.bdiff()

This doesn't look nice, but I don't know how to make a zero-copy slice of
bytes which is compatible with the buffer protocol.

#require test-repo jshint hg10

  $ . "$TESTDIR/helpers-testrepo.sh"

run jshint on all tracked files ending in .js except vendored dependencies

  $ cd "`dirname "$TESTDIR"`"

  $ testrepohg locate 'set:**.js' \
  > 2>/dev/null \
  > | xargs jshint
