Documentation should make it clear that x-add-key must be followed by a blank line
When using x-add-key:
to submit an armored key, it does not (always?) work unless you leave a blank line between x-add-key:
and -----BEGIN PGP PUBLIC KEY-----
.
Since MUAs tend to reflow paragraphs this is probably sensible, but the documentation should mention it. :-)
