PDF information issues

Poking around my system today, I noticed two interesting things about
the PDFs generated by LilyPond.

1) There is no metadata associated with the PDF.  Well, the producer
and creator are set to the appropriate software.  However, when a
top-level title is available (for a book or a score), it would be cool
to embed that in the PDF.

2) Conversely, the editing URIs embedded in the PDF represent a
security risk.  If I share a PDF created with LilyPond, full absolute
file paths from my computer are exposed.  Admittedly, this is a very,
very small risk, but it is still one to consider.  I could not find a
command-line option to disable this; an option to make the paths
relative would also be useful, I think.

I realize that strictly, LilyPond generates PostScript, and that
GhostScript then handles the conversion to PDF; however, this is
information that could be changed in the PostScript as intended for
passing through that conversion.

Does anyone else have thoughts about this?
