Code review comment for lp:~doxxx/bzr/mergetools

The way the merge tools are stored in the bzr config has changed now. Instead of just a list of command-lines, it's now one option which contains a list of tool names and an option named for each tool which contains the command-line. Additionally, the command-lines are stored in list form to preserve spaces within arguments. This does make it a little less user-editable. I could change it back to storing as a simple string but then I'd have to check and quote arguments that contain spaces.

Any comments?
