- * Rename detection logic in "diff" family that is used in "merge" has
- learned to guess when all of x/a, x/b and x/c have moved to z/a,
- z/b and z/c, it is likely that x/d added in the meantime would also
- want to move to z/d by taking the hint that the entire directory
- 'x' moved to 'z'. A bug causing dirty files involved in a rename
- to be overwritten during merge has also been fixed as part of this
- work. Incidentally, this also avoids updating a file in the
- working tree after a (non-trivial) merge whose result matches what
- our side originally had.
