Seems like it's too complicated in vim.  Emacs does this much easier
(IMHO).  Or use Perl, as someone suggested, if you are sure that all
files need to be unconditionally edited.  For simple non-interactive 
replaces, a simple batch file or a shell script which loops through all 
the files and edits them with Sed would be enough as well.
