revset: build _syminitletters from a saner source: the string module For now, these sets will be unicode characters in Python 3, which is probably wrong, but it un-blocks importing the module so we can get further along. In the future we'll have to come up with a reasonable encoding strategy for revsets in Python 3. This patch was originally pair-programmed with Martijn.

mq: release lock after transaction in qrefresh The transaction should be closed within the lock.

perf: release lock after transaction in perffncachewrite The transaction should be closed within the lock.

pull: grab wlock during pull because pull might move bookmarks and bookmark are protected by wlock, we have to grab wlock for pull :-( This required a small upgrade of the 'lockdelay' extension used by 'test-clone.t' because the delay must apply to a single lock only.

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.
