Bug: cherry-pick & submodule




I faced an unexpected behaviour during cherry-picking
a commit to a branch with a submodule.

Git graph:

A -- B [master]
 \
  `- C -- D [test]

Both branches have a file with name `a_file`.
It has been added by commit A.
Commits B and C add a folder with name `a_submodule` to the respective branches.
Commit C does it regularly by adding a file with name `a_submodule/content`.
Commit B adds a submodule with name `a_submodule`.
Commit D only modifies `a_file`.
Note that `a_file` and `a_submodule` are not related.

[repo]
  |- a_file
  `- a_submodule

When I trying to cherry pick commit D on commit B, I got
a conflict with `a_submodule`. Changes of `a_file` are
successfully cherry-picked.

I expected, that there would be no conflicts.

A bash script reproducing the bug is attached.

Vasily.
