page-number overwrites tagline

[Werner]

Hello,

with the modified example of the doc
\paper {
  print-page-number = ##t
  print-first-page-number = ##t
  oddHeaderMarkup = \markup \fill-line { " " }
  evenHeaderMarkup = \markup \fill-line { " " }
  oddFooterMarkup = \markup { \fill-line {
     \bold \fontsize #2 \on-the-fly #print-page-number-check-first
     \fromproperty #'page:page-number-string } }
  evenFooterMarkup = \markup { \fill-line {
     \bold \fontsize #2 \on-the-fly #print-page-number-check-first
     \fromproperty #'page:page-number-string } }
}

I was happy to get the page-number centered at the bottom.
But unfortunately it overwrites the tagline, which should (at least I would like
that) appear at the last page above the page-number.

So my standard-tagline
\header {
tagline = \markup \fontsize #-2 
"Notensatz mit dem freien Programm LilyPond (www.lilypond.org)"
}
is lost.
