We emit this currently:

    $ git -c http.pinnedPubKey=sha256/someNonMatchingKey ls-remote https://github.com/git/git.git
    fatal: unable to access 'https://github.com/git/git.git/': SSL: public key does not match pinned public key!

And with this change, this:

    $ git -c http.pinnedPubKey=sha256/someNonMatchingKey ls-remote https://github.com/git/git.git
    fatal: unable to access 'https://github.com/git/git.git/' with http.pinnedPubkey configuration: SSL: public key does not match pinned public key!

I.e. this replaces a generic error message from curl with something that
points the user at the config variable in question.
