[La0]

Fix this bug

[sylvestre]

Oh, Python :)

[marco-c]

Could you check what is the patch generated by clang-format like here? Maybe we are missing something

[La0]

The parsed patch provided by parsepatch is:

# file: netwerk/protocol/http/nsHttpHandler.h
{'added': [], 'deleted': [426], 'touched': [], 'new': False}

The raw patch is:

Maybe we should consider deleted lines too then?

[La0]

Yeah that's why I added @calixteman on this issue: is there a reason the deleted lines are ignored ?
