Incorrect usage of git unpack-file and merge-file

[dubreuia]

I don't know why, but while executing git octopus I get the following error. It doesn't break anything and the execution continues. It seems to happen on a .xls which git sees as a binary file

Trying simple merge with refs/remotes/features/AMX-11904_Assu2000_integration_F115
Simple merge did not work, trying automatic merge.

Binary files differ

I'll try to post steps to reproduce from a clean repo

I would say that git-apply-conflict-resolution detects the binary conflict as a "UU" text conflict here https://github.com/lesfurets/git-octopus/blob/master/src/git-apply-conflict-resolution#L40
"UU" means "file modified by both sides".
git status --porcelain may tell us if it's a binary conflict
