  * diff3 is part of diff, so obviously generates a conflict.

  * CVS merging is built on top of gnu diff, so obviously generates a
conflict.

  * "merge" is part of RCS, so might be independent from gnu dif, and
generates a conflict.

  * pcdv merge (Codeville's new merge algorithm) generates a conflict
because it requires one line of context.

  * darcs generates a correct merge (because it's lucky). This was a
bit of a surprise to zooko, who thought that darcs would generate a
conflict on parallel changes to adjacent lines.

  * Bitkeeper generates a correct merge (again, because it's lucky).

That's about 50/50 by straight numbers, but the first two are in much
greater use than the rest, and I'm not sure if darcs's behavior is 100%
intended.
