vim.vim syntax highlighting bug when option string starts with 'z'

[GoogleCodeExporter]

I came upon this in the following manner.  In my vimrc, I added colorscheme 
zenburn.  The colorscheme is correctly highlighted, but the 'z' in zenburn 
doesn't appear to be correct. (See attached screenshot)  Checking the 
highlighting rules that are applied, the z was 'VimIsCommand,vimCommand' while 
the remainder of the word is 'vimIsCommand'.

It appears that in revision 916c90b37ea9adbe7dc1e866f85c6e5b49cfba25 
http://code.google.com/p/vim/source/detail?spec=svn916c90b37ea9adbe7dc1e866f85c6
e5b49cfba25&r=916c90b37ea9adbe7dc1e866f85c6e5b49cfba25 , the regex for 
vimCommand was changed and this leads to the bug.  Is there a distinct reason 
for that change, or should it be reverted back or modified somehow?

Still seems to be an issue. CC'ing Charles, as he is the maintainer of the vim 
syntax file.

I think this patch fixes it:

This bug has been fixed for awhile; looks like I neglected to close it.

This change is not in the distribution yet.  Perhaps you need to send your Vim 
syntax file to me?
