[RFC]: Issue 2818 CL cherry-picking UI

Regarding Issue# 2818: "Provide a 'merge' API which allows for merging
of arbitrary revision range"

I've got the API change portion about ready to go and want to get some
agreement on what the CL UI would look like (this will partially support
the MT cherry picking requirement
http://svn.collab.net/repos/svn/trunk/www/merge-tracking/requirements.ht
ml#cherry-picking).

I think dlr's initial off the cuff suggestion in the initial issue
description, support both multiple ranges/revision ranges for both -c
and -r using a comma separated list, is the right way to go, e.g.:

  svn merge -c 4,-6,8,9,10,11,12,-20,-21,-22

  svn merge -r 3:4,6:5,7:12,22:19

IMHO supporting the use of both -r and -c at the same time would also be
nice since it allows a user to cherry pick changesets in the most
concise way...

  svn merge -c4,-6 -r7:12,22:19

...but I'm not going to fight to hard for that if folks don't like it.

The work I've already done compacts these ranges into their minimum
representation, so no need to worry about overlapping ranges, or ranges
that fully or partially cancel each other out -- If a user really wants
to merge -r5:7,7:5 we'll let them, but we'll be smart enough to not
actually do anything.

Any thoughts, alternate suggestions, and/or objections are appreciated.

Paul
