In a normal environment without any namespace, get_git_namespace()
will return an empty string, which is not "refs/namespaces/", so we
create a symref HEAD (that is .git/HEAD) that points at whatever
name the command is about. And this is done every time any ref is
updated, flipping the HEAD to point at whatever was pushed the last,
isn't it?
Why is this a good change? I am puzzled...

This adds decl-after-stmt.
Going back to the proposed log message...

What this paragraph describes is entirely correct, I think. But I
do not think receive-pack is the "we" in that paragraph.
When setting up a "namespace" a and b, shouldn't you be doing
essentially
r=refs/namespaces/
for ns in a b
do
git symbolic-ref $r$ns/HEAD $r$ns/refs/heads/master
done
or something, which is an equivalent to what "git init" does to a
normal repository?
