applying mlock patch to vim 7.0

[Konstantin Rozinov]

Hey folks,

I have several questions about Jason Holt's mlock patch 
(http://www.lunkwill.org/src/vim_diffs/mlock.patch).  Sorry if they're a 
bit loaded...

1.  Has anyone successfully applied it to the current stable version of 
vim-7.0?  I've applied it to the beta vim-7.0157 about a year ago and could 
run vim and :set mlock.  But now I just downloaded the stable version of 
vim-7.0 and finished applying the mlock patch.  After a configure and make, 
running vim and trying to :set mlock fails.

2.  Does the mlock patch change all the necessary places that need to be 
changed in vim-7.0?  Or are there other spots that need changing?

3.  What would be the proper way to add the :set mlock command to vim-7.0 
and making sure that the mlock code is actually called?  Is there a 
standard way of adding new commands?

Thanks,
Konstantin
