Yes. The benefit that I am hoping to achieve is to avoid spawning a
GUI merge tool for files which can be merged automatically via
Subversion's built-in diff3 library, but spawn a GUI merge tool
*during the merge* as-needed for files which require manual
intervention to merge.

Does Subclipse already work in a similar fashion? Perhaps the merge
is automated, but you come back and manually resolve the conflicts
using the GUI merge tool?

Right. While this was not part of what I was originally proposing,
it's certainly an interesting idea. I think we should file this as an
enhancment.
