help: present boolean arguments as "--[no-]foo"

This should make it much more discoverable (we document it in `hg help
flags`, but most users don't think to look there).

Note that flags that default to None (and not False) will not get this
new presentation. We can change the defaults to False later for flags
where it makes sense (probably almost all boolean flags).

create source repository

  $ hg init repo
  $ cd repo
  $ echo a > a
  $ echo b > b
  $ hg ci -Am addfile
  adding a
  adding b
  $ cat "$TESTDIR/binfile.bin" >> a
  $ cat "$TESTDIR/binfile.bin" >> b
  $ hg ci -Am changefiles

make another commit to create files larger than 1 KB to test
formatting of final byte count

  $ cat "$TESTDIR/binfile.bin" >> a
  $ cat "$TESTDIR/binfile.bin" >> b
  $ hg ci -m anotherchange

don't sit forever trying to double-lock the source repo
