This is my first review. It can contain some mistakes.

Mention about GSoC in the notes section (the one followed by the 3
dashes ie. "---") rather than in the subject.

A general convention followed by git users it to write the commit
message as "What he did to the code?" rather than "What problem was
there in the code?" And of course after writing what you did to the
code, you can definitely mention what problem in the code made you do
this change.

Maybe you could describe a little more on why this change is required?
Why would the user want to know "How to use the command?" when the
actual problem is that SHA-1 checksum has been compromised? And I
don't see any consumers of this method which *directly* interact with
the UI.

It seems that PATCH 1/3 and PATCH 2/3 are missing.
