copies: add matcher parameter to copy logic This allows passing a matcher down the pathcopies() stack to _forwardcopies(). This will let us add logic in a later patch to avoid tracing copies when not necessary (like when doing hg diff -r 1 -r 2 foo.txt).

treemanifest: extract parse method from constructor When we start to lazily load submanifests, it will be useful to be able to create an treemanifest instance before manifest data gets parsed into it. To prepare for this, extract the parsing code from treemanifest's constructor to a separate method.

manifest: duplicate call to addrevision() When we start writing submanifests to their own revlogs, we will not want to write a new revision for a directory if there were no changes to it. To prepare for this, duplicate the call to addrevision() and move them earlier where they can more easily be avoided.

record: add message when starting record's curses interface We are adding this log message to reduce a confusion when a command prints something just before starting the curses interface. Since the interactive mode is taking over the entire screen, starts with no delay and does wait for a key press, the user believes that messages printed before opening the interactive mode were actually printed after using interactive mode, not before. The fix adds the line "Starting interactive mode" helping the user separate the messages that were printed before and after the start of the interactive mode. One particular example where this was a problem is the revert command where we first print the list of changes to be considered for revert, then opens the curses interface right away without letting the user see the messages. The user then selects the changes, validates and then see the messages from before opening the interactive mode and is confused.

subrepo: add include/exclude support for diffing git subrepos Previously, git subrepos were ignored if any type of path selection was done. This can be solved by using subrepo status and filtering matching files.

revset: undocument wdir() until its command outputs get stable wdir() implementation is still incomplete and shouldn't be advertised to users. This patch will be backed out when - template values such as {rev} and {node} are settled - major commands and revsets work without crashing

linkrev: fix issue with annotate of working copy The introrev was appearing as None in new annotate tests, which the code from the stable branch wasn't expecting.

merge with stable

histedit: delete all non-actionclass related code Now that all actions have been migrated to the class format, we can delete all the unnecessary code that supported the old function format.

histedit: improve roll action integration with fold Previously the fold action would inspect it's class to figure out if it was a rollup or not. This was hacky. Now that finishfold is inside the fold class, let's modify it to check a function (which roll can override) to determine if it should be prompting for a commit message.
