Good idea. By the way, is it replacement for RCS merge, i.e. is it
file-level merge tool, merge.onefile rather than merge.tool? What happens
if there are multiple merge [contents] conflicts: is merge.tool invoked
in parallel for each conflict, or is it waiting for earlier merge.tool
to finish (well, in which case we can always do set merge.tool to 
"<program> &")? And is merge.tool invoked for recursive part of recursive
merge strategy? This merge startegy depended on resolving conflict
markers, i.e. had built-in knowledge of 'merge'/'diff3 -E' output.

Besides, it would be useful not only to spawn interactive merge tools,
but also to use mergers specific for file-type, for example 3DM or xmlcmp
tools for merging XML files.
