[xml/sgml-pkgs] Bug#676717: dh_installcatalogs transition and w3c-dtd-xhtml removal bugs

[Osamu Aoki]

Hi,

Thanks for completing sgml-base transition.  Here is some comments on
sgml-base from an outside observer.

Since you got enough impressive people, you can treat this as just FYI
and non-blocking comment.

This is non-essential but I thought it may be good idea not to make
postinst script robust.  As it is written now, any non-zero exit code of
update-catalog will break postinst script.

Why not like:
       update-catalog --quiet --update-super ||
       echo "SGML catalog is broken. Read /usr/share/doc/sgml-base/README.trouble." 1>&2

This way, postinst will not stop and it will not be quiet when it should
not be.  It will not stop installation.  I may be wrong here.... though.

FYI: I did not understand why this script returns 
 * 1=error for normal errors, 
 * 0=non-error for goods and 
 * -1=error (for shell this 255) for --help and --version. 
The last type was not expected.
