Comment #3 on issue 1650 by [email protected]: using multiple \header
in a block prints only the latest items

Issue 1650: Multiple header blocks shall be merged rather than replace a
previous one
If there are two or more header blocks at top-, book-, bookpart- or
score-level,
the settings of all header blocks are merged. If a value appears in multiple
blocks, the last assigment wins.
