Fix auto-generation of quilt.1 to work with dash

 The echo command of dash interprets \f as a special characer and
 thus generates a bad manual page. bash's echo leaves them unchanged
 (it needs -e to replace those special characters). Using printf
 instead is a portable solution that work with both shells.
 .
 The code also uses a bashism ($'') but it's not really needed with
 GNU sed at least (it understands \t and \n) so drop it and avoid some
 painful double escaping.
 .
 This patch was written by Raphael Hertzog for the Debian package, and
 updated by Martin Quinson so that it applies on lastest upstream
 sources.
