The colon in that syntax is flat wrong.  But branch deletes won't
automatically propagate between repositories.  I do things like this
all the time:

git branch -d REL8_4_STABLE

Doesn't delete it from the master at all, and I can recreate it
whenever I like using:

git checkout REL8_4_STABLE

In fact, even I do this, it's harmless:

git branch -r -D origin/REL8_4_STABLE

Because it'll be undone the next time I do this:

git pull

Now, there IS an incantation to destroy a branch from the upstream
repository (using git push with an argument) but even if that
happened, it wouldn't propagate to cloned copies, so someone else
could easily put it back.
