Patch Set 1: I would prefer that you didn't submit this

(2 inline comments)

Please see my inline comments

I see two additional issues:

- If I open the Create Branch... dialog on the context menu of the currently checked out branch I would like to keep this branch as source.

- When I open the Create Branch... dialog on the context menu of a remote branch or a tag I get a proposal for the new branch name. I do not get it now for the branch which is determined from the config constant "defaultsourceref".
