 function, so that less of the code needs to change.  But I'd say that it's
 our call in this case though.

 If anything I would be tempted to put the old behavior in a function that
 explicitly adds multiline output since that's a PEM-ism (and OpenSSL's PEM
 output flavor as well).  I think what's in the branch is clear enough
 though.

 I amended a commit so I can give the autosquash thing a whirl, you might
 need to re-pull. (There's also one more commit past what you've seen that
 fixes up a doxygen comment).
