Comment # 1 on bug 1202885 from Niklas Lindstr���m

This appears to have been resolved by revision 320, which updates vim to
version 9.0.0313. That includes a fix described as '"make install" does not
install shared syntax file. (James McCoy)'.

As I understand it, there is thus no need to update vim.spec (as I previously
guessed), as the bug was from upstream, fixed there and included in a new
revision. I hope it is OK that I'm changing the status to "RESOLVED" "UPSTREAM"
here.
