You are answering "What is 'refs/' good for in the pathnames of files
that store loose references?" I was asking "What is 'refs/' good for in
the logical names of references?"
It would have been totally possible to make the full name of a branch
be, for example, "heads/master" and nevertheless store its loose
reference in "$GIT_DIR/refs/heads/master". The obvious place to store
HEAD in such a scheme would have been "$GIT_DIR/refs/HEAD" while still
calling it "HEAD". This could have avoided the problem that we now have
with pseudo-references like FETCH_HEAD being stored directly in $GIT_DIR.
I see; OK.
