Merge branch 'jk/push-force-with-lease-creation' into maint
"git push --force-with-lease" already had enough logic to allow ensuring that such a push results in creation of a ref (i.e. the receiving end did not have another push from sideways that would be discarded by our force-pushing), but didn't expose this possibility to the users. It does so now. * jk/push-force-with-lease-creation: t5533: make it pass on case-sensitive filesystems push: allow pushing new branches with --force-with-lease push: add shorthand for --force-with-lease branch creation Documentation/git-push: fix placeholder formatting
