Merge my branch to `devel`

Let's say I have branch send-stats, and I have couple of commits which I need to squash and merge to devel branch.

Follow these steps:

git checkout send-stats - switch to my branch
git rebase -i devel - rebase interactively relatively to devel, here we need to squash all commits to the first one
- in vim: :2,$s/pick/f/ - relaces picks to f for every line except first one - indicates those commits as 'to squash'
- save
git push -f upstream - push upstream to origin, changing history
git checkout devel - switch to devel
git pull - what if origin/devel changed? pull it!
git checkout send-stats - back to my branch (this awkward moment you jump between branches for no good reason)
git rebase origin/devel - put newly squashed commit on top of devel branch
git push -f - not sure if we need it, but let's rewrite the history once again
git checkout devel - I know, back there
git merge send-stats - finally!
git push - uhhh, it was a long day
git push origin :send-stats - that's how we delete the branch in git :(

In case of commiting all commits with history make sure you get extra commit of merging meaning there is no fast-forward: use key --no-ff
