Just a minor nit, but reacting to recent "passive-aggressive"
message change in another thread, perhaps we should stop asking a
rhetorical question like the new message and instead state what we
detected and what we consider is an error condition as a fact in
them.

The last die() in the above helper function used to be such a
rhetorical question "--merge without HEAD?" but now it reads much
better.  The one about symbolic ref is new in this series, and we
can avoid making it rhetorical from the get go.  Perhaps "%s exists
but it is a symbolic ref" or something?
