Not sure I understand the problem.  The metadata file is getting
created but not "written"?  So it's empty or something?  What is the
file name?  It shouldn't be quoted if it is on the linux side.

This would actually be a pain to add because rdiff-backup deals with
files which have filenames, metadata, etc.  Most of the functions deal
at that level of abstraction.

So instead of restoring $RESTORE_IN to stdout, why not write a script
that goes like this:

rdiff-backup -r xxx $RESTORE_IN $TEMP
cat $TEMP
rm $TEMP

There may have to be a temp directory, but the users don't have to
know about that.  I guess the problem is temp space?

Will keep this message unread and get back to 3 in a bit hopefully.
