bisect: extra a small initialisation outside of a loop Having initialisation done during the first iteration is cute, but can be avoided.

pycompat: only accept a bytestring filepath in Python 2

py3: use raw strings in line continuation (convert ext) Our py2 to py3 string translations marks those as bytestrings.

py3: namedtuple takes unicode (journal ext) namedtuple usage consistent with changelog.py:141

debuginstall: use %d instead of %s for formatting an int % formatting on bytes on Python 3 is pickier about which % character we specify.

py3: test to check which commands run This test helps us to keep track on the commands which runs to Python 3. The full traceback is hidden. Thanks to Augie and Martijn to wrap it up in four lines.

bisect: build a displayer only once There is multiple spot using this, building it early will help to extract more of the logic into the bisect module.

bisect: factor commonly update sequence For now, This remains a closure in the module to avoid circular import with used module.

bisect: move check_state into the bisect module Now that the function is simpler, we resume our quest to move the logic into the bisect module. In the process, we add basic documentation.

bisect: simplify conditional in 'check_state' Now that extra code about "updating" flag have been removed, we can simplify the condition flow and remove a level.
