Help with d.vim Syntax file for Vim

[ulyssesdwolfe via Digitalmars-d-ide]

Hi,

There seems to be some missing statements in the standard d.vim 
that gets distributed with vim regarding auto-commenting.
Whenever I am in a multiline comment for example a ddoc statement 
and start a new line by hitting the Enter key, the result is an 
indentation of 1 on the new line and no comment char unlike the 
syntax in normal c and cpp files. It doesn't matter if the 
comment start was with '/**' or '/++'.

I took a look at the runtime/syntax/c.vim for hacking the 
auto-commenting out of that file and putting it in d.vim. But I 
am not familiar with any of those calls.
I was wondering if someone who is more familiar with Vimscript 
can tell me what lines or quick fix I need to put in the syntax 
file to get the auto-commenting to work for d editing.
