Hello John,
Please note that Debian has no requirement that debian/copyright
be machine-readable. The new format 1.0 is completely optional.

But this is not the case, so GPL 2+ is fine.
The FTP masters do not require this to be mentioned.

Note that these files are not used by Debian build process,
and the file explicitly allow sublicensing to GPL2+.

PARI predates the GNU GPL so this is not surprising.
However PARI as a whole is distributed under GPL 2+ as stated in the
README and the COPYING file.
Making copyright files more complex without neccessity is not beneficial
to Debian.
Thanks for using Debian!
Bill.
