I'm sorry to edit the NR section on output file metadata so soon after
Issue 4921 was fixed, but that issue actually reminded me about the
missing documentation for the "midititle" header variable (which can be
used to set the sequence name for MIDI files independently of the
contents of "title"), so here's a patch to generalize the section on
output file metadata (to not speak only of PDF files; I hope the point
of Issue 4921 is still clear enough), and add the missing piece of

+type, and blocks higher in the block hierarchy, will be consulted.
+Therefore, for PDF files, only the @code{\book} level and the top level
address@hidden definitions affect the document-wide PDF metadata, whereas
