Experimental support for a comment in the files' preamble in extraction.
Scheme comments are output on a single line because Ocaml's Format
module which serves as a backend to Pp has an integer, rather than a string
as identation value, so we cannot make it so that each new line in the
comment starts with ";; ".
I've tried something with Pp.ifb but it was hackish at best and had somewhat
strange results.
Known bug: as Pp.std_ppcmds is non-persistent, the comment is actually printed
only once per Extraction command, even if it outputs several files.
