Generate proper listing and summary in git patches

[krnowak]

It's about generating stuff like:

 test.sh                               |  1 +
 tests/basic/expected/0001-Add-b.patch | 16 ++++++++++++++++
 tests/basic/expected/0002-Add-c.patch | 17 +++++++++++++++++
 tests/basic/expected/ADD_B.patch      |  5 -----
 tests/basic/expected/ADD_C.patch      |  6 ------
 tests/basic/expected/patches.list     |  8 --------
 6 files changed, 34 insertions(+), 19 deletions(-)
 create mode 100644 tests/basic/expected/0001-Add-b.patch
 create mode 100644 tests/basic/expected/0002-Add-c.patch
 delete mode 100644 tests/basic/expected/ADD_B.patch
 delete mode 100644 tests/basic/expected/ADD_C.patch
 delete mode 100644 tests/basic/expected/patches.list

For first iteration I will be happy if 16 ++++++++++++++++ looks like 16 +.

This needs to take very long paths into account. I think that they are truncated if too long.
