help: move "revision syntax" help topics into online help Move the "Specifying Single Revisions" and "Specifying Multiple Revisions" help topics from the manual page into the helptable so they are available both online and in the manual page.

help: helptable is an ordered collection The helptable is used for helptopics listed in the manual page, so the order of topics should not be random. Convert it from a dictionary into a tuple of tuples. Also reorder helptable entries to keep previous manual page order.

help: list special help topics with -v

help: enable listing of a subset of the command list Instead of giving the "command %s is ambiguous" error message with a bare list of possible command, display help list for all commands starting with the given string.

addremove: correctly handle intermediate symlinks This fixes problems mentioned in issue660 comments (unrelated to original issue) where directory was renamed, and symlink was added instead. In such situation addremove wasn't able to correctly detect that old files no longer here, but tried to add symlink (and failed due collision with old files).

drop superfluous param from revlog.addgroup()

copies: teach copies about dirstate.copies When we're using copies() to find changes between the working directory and its first parent for diff/status/etc., use dirstate.copies() directly. This avoids doing a full statwalk for simple diffs (issue1090) and removes a special case from the status command.
