For the D programmers that use vim as their editor, I have updated the
vim syntax file to match version 0.79 of the D spec.

  http://www.vim.org/scripts/script.php?script_id=379

I don't get a chance to code in D much, hence the syntax file does not
get tested thoroughly. If anyone finds bugs in it, or want to make
additions to it, please contact me.
