Log:
debian/xserver-{common,xfree86}.preinst.in: rework migration logic:
- create the configuration file auxiliary directory /var/lib/xfree86
on all installs and upgrades if it doesn't already exist
- don't throw a warning if the path to the auxiliary directory exists
but
is not a directory; assume local admin cleverness
- don't migrate a configuration file if its debconf region markers have
been removed
debian/NEWS.Debian: fix up NEWS.Debian entry to describe additional case
where files are not migrated (debconf region markers removed)
