How to make the copyright notice appear with the tagline

[Romel Anthony S. Bismonte]

Hi again, all,

I know that the copyright notice will appear in the footer of the first 
page, and the LilyPond tagline will appear in the footer of the last page. 
But what about if the piece were only one page long? I decided to customize 
oddFooterMarkup in my ly file:

\version "2.10.25"

#(set-global-staff-size 24)

melody = \relative c'' { c d e f }
text = \lyricmode { Do Re Mi Fa }

\paper {
   #(set-paper-size "letter")
   line-width = 7.5\in
   %between-system-space = 2.0\cm
   %head-separation = 1.0\cm
   %between-system-padding = #1
   printallheaders = ##t
   oddFooterMarkup = \markup { \column {
       \line { \fromproperty #'header:copyright }
       \line { \fromproperty #'header:tagline }
   } }
}

\score {
   <<
       \new Voice = "one" { \melody }
       \new Lyrics \lyricsto "one" \text
   >>
   \header {
       title = "Title"
       subtitle = "Subtitle"
       composer = "Me"
       copyright = "Copyright Information"
   }
   \layout { }
}

My intent is for both the copyright and the tagline to appear on the bottom 
of this one-page piece. This file renders fine, but the copyright does not 
appear. Since "printallheaders" is set to True, I do not see what else I am 
forgetting to set or unset here.

I've been wondering how to do this since I finished my first piece, but 
until now I've been able to sidestep the issue because most of my pieces had 
been longer than one page. Perhaps 2.11.* renders this the way I expect? ^_^

Any help would be appreciated. Thanks for the help.
