- various clean-ups to pacify rpmlint:
- uses spaces instead of tabs consistently
- mark %{_datadir}/emacs/site-lisp/pari/pariemacs.txt as %doc
- mark %{_datadir}/pari/{PARI,doc,examples} as %doc
- fix permissions of gp
- don't strip gp so we get debuginfo for it
- move here documents out to separate source files
- make gp subpackage require same version-release of main package
- apply patch from Patrice Dumas to use xdg-open rather than xdvi to
display DVI content, and move the xdg-open requirement from the main
package to the gp sub-package (#530565)
