inhibit: fix devel warning _inhibitmarkers was taking a transaction without the proper lock. Adding the lock removes the warnings.

evolve: add -i flag to amend command The -i flag was missing because it is not a global flag of the commit command. We can't make it a global flag yet as it is used in many places where it would not be appropriate so we just add it for this occurrence. Also, we only want to add it when commit supports it (otherwise it wouldn't work with older versions of mercurial)

prune: prune fix transaction pattern I forgot to amend.

prune: fix pruning w/ bookmarks and inhibit Previously prune would create the obsolesence markers, then try to fix up the bookmarks. With inhibit enabled, the act of closing a transaction for the bookmark step caused it to unhide commits that were trying to be pruned. The fix is to put the whole thing in a transaction.

inhibit: remove book -D dependency on cmdprune Bookmark -D was relying on the prune command to be registered, which isn't the case if we've disabled evolve commands. Instead, let's just hard code the arguments. The real fix would be to abstract away the 'I want to prune commits' functionality in evolve to a reusable function, but this will do for now.

inhibit: wrap repo.commit to inhibit nodes Rebase was failing if you rebased a commit, stripped it, then rebased it again. This is because the node was still hidden and we needed repo.commit to uninhibit it.
