Instrument alignment in page head (v2.4.2)

[Thies Albrecht]

Hi everybody!

I wonder if anybody ever got aware of the fact, that the instrument name 
in the page head isn't exactly centered. Depending on odd or even page 
it is put a little to the right or left.

You can verify this, when compiling the following code and comparing 
page head of p.2-3:

<begin of code>
\header {
        instrument = "Instrument"
}

\score {
        \relative c'' {
                \repeat unfold 30 {
                        s1 \break
                }
        }
}
<end of code>

I could manage to center it changing page-layout.scm. As I said... just 
wondering if anybody got aware of it.

Kind regards
