Hmmm... I wonder how well git manages that (merge with renamed directory).

  folder1/a  -->  folder2/a  --------> folder2/a
  folder1/b  -->  folder2/b       /    folder2/b
      \                          /     folder2/c
       \------->  folder1/a  ---/
                  folder1/b
                  folder1/c


I wonder how bzr manages "separate some files into subdirectory" (and how
well git does that), i.e. we have

   sub-file1
   sub-file2
   filea
   fileb

In the 'main' branch we separated "sub-*" files into subdirectory

   sub/file1
   sub/file2
   filea
   fileb

How would that merge with adding new sub-* file on the branch to be merged?

   sub-file1
   sub-file2
   sub-file3
   filea
   fileb


Or how bzr manages sub-level movement, such as splitting file into two,
or joining two files into one file.


P.S. is anyone working on --follow option for renames following path
limiting?
