commands: adding --no-status to resolve to match status

commands: use rev from remote repo when updating as part of a pull

commands: highlighting that rev is based on the remote repository

bookmarks: use API to determine if repo is local

diffstat: with --git, mark binary files with Bin Normally, diffs without any text insertions or deletions are reported as having 0 lines changed by stock diffstat. Compatibility is preserved with stock diffstat in this case, but when using --git, binary files are marked with Bin as a means of clarification. git diff --stat does something similar, though it also includes the old and new file sizes.

color: colorize diff --stat

diff: add --stat for diffstat output diff/qdiff --stat invokes patch.diffstat() on the diff output. When in interactive mode, the output's maximum width is determined by the terminal's width.

diffstat: print 0 instead of nothing for 0 adds or removes This is in line with how the stock diffstat behaves when processing a single diff with no line modifications (like a binary diff).

update tcsh_completion for the new forget and summary commands

cmdutil: minor refactoring of changeset_printer._show - use ctx.branch() instead of directly accessing the extra field "branch" - move definitions of locals ('extra' and 'branch') down to where they are used
