Bug#3026: xbase et al postinst doesn't flush stdout

[Lukas Nellen <lukas@teorica0.ifisicacu.unam.mx>]

Package: xbase
Version: 3.1.2-8

This bug seems to affect a lot of the X11 related packages.

The postinst makes a call to /usr/sbin/xbase-configure and through
that /usr/bin/X11/xf86config. At least one of those programs doesn't flush
its output after each line. This leaves you without any visible clue
of what is happening when you pipe the output of dpkg during the
installation of this package - try configuring X11 without any prompts
:-).

                        cheers,
                                Lukas
