bisect: move 'printresult' in the 'hbisect' module The logic is already extracted into a closure. We move it into the module dedicated to bisect. A minor change is applied: the creation of the 'displayer' is kept in the main command function, it remove the needs to import 'cmdutil' in 'hbisect'. This would create an import circle otherwise.

bisect: move the 'extendrange' to the 'hbisect' module We have a module ready to host any bisect logic. That logic was already isolated in a function so we just migrate it as is.

bisect: extract the 'reset' logic into its own function This is part of small clean up movement. The bisect module seem more appropriate to host the bisect logic. The cleanup itself is motivated by some higher level cleanup around vfs and locking.

bisect: access the filesystem through vfs when reseting We have nice and shiny abstractions now.

util: remove the copypasta unquote function The _urlunquote function was added back in the day to improve startup performance, but this version is a) not compatible with Python 3 and b) has quadratic performance issues that Python core solved eons ago. Moreover, the function moved from urllib to urlparse (cheaper to import) *and* that module is already imported into pycompat. As a result, removing this function improves perf now. Before: ! wall 0.066773 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) After: ! wall 0.065990 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)

merge: add conflict labels to merge command Now that we present the conflict labels in prompts, it's useful to have better names than "local" and "other" for every command.
