filectx: allow custom comparators We're going to introduce other sorts of filectxes very soon, and we'd like the cmp method to function properly (i.e. commutatively) for them. The only way to make that happen is for this cmp method to call into that specialized one if that defines a custom comparator.

debugmergestate: print out record type for files We're going to add a separate record type for change/delete conflicts soon. We need to make sure they get stored with the correct record type so that older versions of Mercurial correctly abort when they see change/delete records.

merge.applyupdates: don't return early if merge driver's conclude failed Somewhat silly oversight -- this prevented the progress bar from being reset.

convert: use repo._bookmarks.recordchange instead of repo._bookmarks.write Before this patch, convert was using repo._bookmarks.write, a deprecated API for saving bookmarks. This patch changes the use of repo._bookmarks.write to repo._bookmarks.recordchange.

convert: indentation change to make the next patch more legible We put the code to be indented in the next patch in a "if True:" block to make it easier to review.

strip: renaming local variables Renaming local variables to be more precise, i want to store a different list of bookmarks and it would be hard to understand what marks represents in that change therefore renaming it to repomarks. Renamed bookmarks(module) to bookmarksmod as to free up bookmarks which will be used when pluralizing bookmark.
