Git --force-with-lease with + in branch (refspec)

Question

On current Git, is there a material difference between git push --force-with-lease origin +somebranch, git push --force-with-lease origin somebranch

Answer 1

which would one should prefer by default when I like to pull to work branch via git pull --rebase origin master?

I reported on force-with-lease in 2013 for git 1.8.5, and March 2016 for git 2.8".

I would say... none of them.
A pull --rebase is done to avoid having to force push (with or without lease) anything.

I simply set (since git 2.6)

git config pull.rebase true
git config rebase.autoStash true

That allows me do do some simple git pull, followed by simple git push (no forced push involved)
