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).

help: show "default: off" for boolean flags that default to off Differential Revision: https://phab.mercurial-scm.org/D5431

help: use "default: on" instead of "default: True" "True" feels like a Python thing and not something that users should see. Differential Revision: https://phab.mercurial-scm.org/D5430

check-commit: disallow capitalization only right after topic It should be okay to write "topic: change 'default: True' to 'default: on'". Differential Revision: https://phab.mercurial-scm.org/D5429

py3: add a b'' prefix in tests/test-remotefilelog-pull-noshallow.t This makes the test pass on Python 3. # skip-blame because just b'' prefix. Differential Revision: https://phab.mercurial-scm.org/D5427

error: implement __str__ on RevlogError to fix some output defects on Py3 We open-code encoding.unimethod here to avoid cycles, and do a local import of encoding when someone str()s a RevlogError. It's not my favorite solution, but it gets the job done. Differential Revision: https://phab.mercurial-scm.org/D5426

perf: add two more missing b prefixes for Python 3 # skip-blame just two more b prefixes Differential Revision: https://phab.mercurial-scm.org/D5425
