Suppress scoreTitleMarkup

[Br. Samuel Springuel]

What is the best way to suppress the default scoreTitleMarkup?  I've 
been using `scoreTitleMarkup = \markup \null` but this is creating an 
extra space above the score (which, with lilypond-book-preamble.ly, 
comes out as an empty "system").  I'm defining a custom titling format 
in which I want to do away with scoreTitleMarkup entirely and only use 
bookTitleMarkup (whose definition is working fine, so I'm not including 
it in the MWE below).  I don't want any extra space where the 
scoreTitleMarkup would normally go (and definitely not an extra system 
when lilypond-book-preamble.ly is used).


#(ly:set-option 'relative-includes #t)
\version "2.19.82"
\language "english"

\include "lilypond-book-preamble.ly"

\header {
    piece = "PRAELUDIUM I"
    opus = "BWV 846"
}

\paper {
        scoreTitleMarkup = \markup \null
}

global = { \key f \major }

music = \relative c' {
    \repeat unfold 16 { c }
}

verseI = \lyricmode {
    \repeat unfold 16 { test }
}


\new Staff
<<
    \new Voice = "mel" { \global \music }
    \new Lyrics \lyricsto "mel" { \verseI }
>>
