%f of gnus-summary-line-format

[Michael Cook]

I'm trying to get %f of gnus-summary-line-format working.
The help text says:

  %f   Contents of the From: or To: headers (string)

So, in my gnus-summary-line-format, I changed the %-20,20n to
%-20,20f.  But that change had no apparent effect in the
subsequently-generated *Summary* buffers.

Poking around in gnus-sum.el, I found the function
gnus-summary-from-or-to-or-newsgroups.  This function uses the
expression `(mail-header-extra header)' repeatedly.  But that
expression always seems to evaluate to nil.  And so
gnus-summary-from-or-to-or-newsgroups just always seems to return
the usual `mail-header-from' value.

Am I misunderstanding how %f is supposed to work?
Or is there a bug here somewhere.

(I'm using nnml groups, pgnus-0.69, and EMACS 20.3.1.)

Read the thread entitled "using multiple Summary buffer formats"

It should explain some of the things you need to do to get %f do what
you want.

Got it.  Thanks.

The help text for %f should probably explain that:

Ah, good point.
I'll submit a patch that removes all the help strings.
Watch this space...

For this particular variable, listing all things that influence all
the format specs is beyond what one can comfortably put in a doc
string.  Doc strings are for easy reference when tinkering -- after
you've read the manual.
