I want to add a couple of new headers to the "gnus-visible-headers"
variable. I could write out all existing headers and then add the new
headers, as in

(setq gnus-visible-headers "existing\\|new").

That works, but is there a simpler way (and shorter) of just appending
the new headers?

Thank you.

Best wishes,

Colin Baxter.
