Subject:    [PATCH v3 3/7] push: copy code to setup_push_simple()

[Download RAW message or body]

In order to avoid doing unnecessary things and simplify it in further
patches. In particular moving the additional name safety out of
setup_push_upstream() and into setup_push_simple() and thus making both
more straightforward.

The code is copied exactly as-is; no functional changes.
