Code review comment for lp:~maxiberta/launchpad/snap-name-extraction

You should set a prerequisite branch if and only if you actually branched from the unmerged branch in question; otherwise you will get very confusing results.

However, you really will need to redo this on top of snap-store-add-edit-views, I'm afraid. The reason is that Snap.name is unique per person, but the same name in snapcraft.yaml may be associated with a snap that exists in multiple series. Defaulting name from what's in snapcraft.yaml will therefore fill in an initial form value that fails validation in some cases, and we shouldn't do that. We must only use this to pick a default for Snap.store_name, not Snap.name.
