new fetch-diff tool - does what it says

Review Request #1467 — Created March 9, 2010 and discarded — Latest diff uploaded



Reviewers support specifying diff revision

add fetch-diff

Add fetch-diff, a tool to grab raw diffs from Review Board using the
same authentication and server-guessing as post-review. For now, only
grabs the latest diff.

Here is a little something to motivate "library-izing" rbtools. I was asked to run an automated build against a review request (our internal Review Board), and I thought, "wouldn't it be great if I could feed the builder a request number instead of making a patch and pointing it at the full path to the patch?". Well, now I can :-).

It is probably more interesting to diff the new script against The only altered functions (I outright dropped a lot of stuff) could be reverted (i.e. use the versions in new, shared code); they just need some options to be set to empty instead, to fix missing variable errors.

Please let me know if the 'git format-patch' patches are wanted (i.e. to preserve the history, tiny though it is).
Works against our internal server, using both git-svn and svn repositories to find the server information; both '#' and '#:#' request formats tested. Also this was posted using including :-).
