I oftentimes find myself working across clones of the same repository, but in different branches. Once code is working in a branch, I want to commit it locally and then (sometimes) cherrypick that diff over to the other branch.

I currently do this by exporting a patch to disk, but it would be really convenient and much faster to support the clipboard.

For example, instead of having the patch destination be a folder, just have it be the clipboard. And ditto for the patch source - then we'd get super easy sharing of diffs across repos.

This is related to SRCTREE-1564.
