[Pkg-fonts-devel] Bug#659550: fonts-beteckna: use dh_installdeb maintscript support

Using 'dpkg-maintscript-helper supports rm_conffile' guards introduces
unreliability into upgrades; it means that the conffile is removed or
not depending on whether dpkg happens to be unpacked before
fonts-beteckna.  This seems generally undesirable; it would be better to
enforce a single code path.  (This is academic for Debian because the
version of dpkg in squeeze supported dpkg-maintscript-helper, hence
Severity: wishlist; Ubuntu's last LTS release didn't have a sufficient
version of dpkg for that which is why I care.)

It would be nice to just use dh_installdeb's support for generating
dpkg-maintscript-helper commands, which was introduced in debhelper
8.1.0.  This would remove duplicate code from your maintainer scripts -
in fact, you'd no longer need to have handwritten maintainer scripts at
all.  Here's a patch:

  * Use maintscript support in dh_installdeb rather than writing out
    dpkg-maintscript-helper commands by hand.  We now simply Pre-Depend on a
    new enough version of dpkg rather than using 'dpkg-maintscript-helper
    supports' guards, leading to more predictable behaviour on upgrades.
