Pari-2.1.5: Doc patches re-applied

[Christian Cornelssen <ccorn@cs.tu-berlin.de>]

Dear Pari developers,

For pari-2.1.1, I once submitted some doc patches which seem to have
made it into the 2.2 branch in the CVS, see

	http://www.parigp-home.de/lists/200108/22aaa

but in 2.1.5 they are not integrated.  I could re-apply the original
doc patches without adaptation, but I have attached them for easier
reference:

1. Fix: refcard.tex gets a wrong \magnification, thus does not fit A4

2. Fix: users.tex produces an empty page 209 where the index should begin

3. Adaptation to (my) RPM setup: Adjust path specifications in
   usersch2.tex

Patch 3 has to be be re-examined for standard pari builds, perhaps it
is unneeded there, or has to be tweaked.

My version of pari.spec is not much different from the one at the
megrez ftp server, but I regularly update my version which you can
find at

Regards,

Christian Cornelssen
