Once again on extra headers

Once again on extra headers

[Harry Putnam]

I've used the cool extra header code for sometime to generate NOV  and
display a "Keywords: " header like this:

     (setq gnus-extra-headers
           '(To Newsgroups Keywords))
     (setq nnmail-extra-headers gnus-extra-headers)

Now I want to use this same technique to generate NOV and display a
custom header `X-HP-Keywords: '.

Using the same code:

     (setq gnus-extra-headers
           '(To Newsgroups X-HP-Keywords))
     (setq nnmail-extra-headers gnus-extra-headers)

And regenerating NOV in that group isn't doing what I expected.  No
X-HP-Keyword header is displayed.  It isn't clear in the manual
section that covers this if this only works with certain headers or if
one can make it work on a custom header too.

There is language there that says:

  2. The value of these extra headers can be accessed via the
     `gnus-extra-header' function.  Here's a format line spec that will
     access the `X-Newsreader' header:

          "%~(form (gnus-extra-header 'X-Newsreader))@"

But I haven't had to do that for the `Keywords' to work.  Is it my
non-regulation header causing the problem or something else.

Displayed where?  Look at the .overview file on the disk -- is the
header in there?  If so, everything worked.  Even if it wasn't doing
what you expected.  (What did you expect?)

Be indiscrete.  Do it continuously.

Keywords is part of gnus-visible-headers.  X-HP-Keywords is not.

The -extra-headers variables will get your new header into overviews,
but you must tweak gnus-visible-headers to get them into the article
display.

Sorry about the poor description...
I checked if they were in there before posting.  They are.

I expected to see those headers appear on one of those long signs
being pulled across the sky by an airplane, over every major city in
the US.  But I see now that I forgot to tweak the 
`gnus-generate-grandiose-header-display' ( he he )

Haa.  I forgot about `gnus-visible-headers'.  Now we're talking
