Is this Debian-specific?

[Santiago Vila <sanvila@unex.es>]

There is a package in main with the following copyright notice:

   Permission to use, copy, and distribute this software and its
   documentation for any purpose with or without fee is hereby granted,
   provided that the above copyright notice appear in all copies and that
   both that copyright notice and this permission notice appear in
   supporting documentation.

   Permission to modify the software is granted, but not the right to
   distribute the modified code. Modifications are to be distributed as
   patches to released version.

   This software is provided "as is" without express or implied warranty.

Appended to this, in the copyright file, there is an email from the
Debian maintainer asking whether it is ok for Debian to distribute this
package as an .orig file plus a patch, and the answer from the author was
"The above scheme is OK with me".

[ The way this is currently worded, license seems Debian-specific ].

If it is not Debian-specific, it is *unreasonable* to ask the author to
reword the license so that permission to distribute modified versions
is allowed as long as the original is distributed as well?

(For details, see Bug #35510).

Thanks.
