I think it might be worth attempting an auto-merge like the above and use
the mechanism you describe in the fallback case. The automerge procedure
needs more thinking out than the outline I've sketched above; we need to look
through the manifest, grep out the etc/defaults files, run 'file' on them to
verify that we only attempt to merge plain ascii text files, back up the old
default config files before unpacking the package tarball, etc. etc....
Can't think of a witty .sigline today....
