I basically added the v:collate variable to be consistent with the other
v: variable, like v:lang and v:ctype and v:lc_time variable and I think
it is easier to get the current locale using those variables instead of
having to redir the :language [type] subcommand.
I remember that I intentionally left out the :sort and sort() functions,
because I wanted to fix the immediate problem first and left the rest
back then alone, wanting to do it later. It seems I forgot :( so thanks
for adding that.

Possible. I suppose if we need those, we can always enhance it further.
