To all remotes which have a relationship to this repo with the 
-respectRemote flag.
Normally, only the blessed remote will have this.

Everytime a branch merges or rebases with a remote repository, it's 
flags the last commit of that remote repository as the pointOfNoReset 
commit.
If local branches merge or rebase with a local branch, the 
pointOfNoReset commit is transitively applied (only the last one wins).
git reset will fail to reset beyond the pointOfNoReset commit, unless 
forced.

Branches that are behind master, will have a pointOfNoReset commit in 
their history, if master goes forward afterwards, that won't affect 
those branches, not until they are merged.

Don't use the -respectRemote flag in the relationship between those 2 
repo's.

Them too. All operations would need to follow the -respectRemote flag's 
limitations, unless forced.

Don't use the -respectRemote flag in the relationship between this repo 
and any other repo.
Or force it.
