We remove the example here about HEAD not being a pseudoref. This
example seems helpful to indicate that a pseudoref cannot be a symbolic
ref. Is this no longer the case and the change intended?

Pseudorefs behaving the same and using the same tooling seems to
contridict the previous documentation. I assume the previous information
was out-of-date, but it might be nice to explain this in the message.

We seem to be inconsistent between using "pseudoref" and "pseudo ref".
Not sure it we want to be consistent here.
