actually have a range built into the script based on some number of
lines relative to the current line. This should be adaptable to
specify a range.

script anymore so I'm not sure if I want to plugin-ify it and put it
on vim.org, since I won't be able to actively maintain it very well.
If I remember, the reason I stopped using it was that the lines
colored by the script made the special characters shown with my 'list'
and 'listchars' setting look like normal text instead of the
highlighting normally applied.

In this particular case, the s: for the function makes sure the
function is only defined for the script (and won't have any naming
conflicts with other scripts). The g:ALTLINES_disable lets you
(temporarily or permanently) disable the line coloring for all
buffers. The b:ALTLINES_disable lets you disable it on a per-buffer
I actually forgot I had this in there. So actually, your initial
question of toggling it on/off for a particular buffer could be as
simple as a BufRead,BufNewFile autocmd which does a :let
b:ALTLINES_disable=1, and a mapping to unlet b:ALTLINES_disable and
either call the function which does the highlighting, or runs an
appropriate doautocmd command.
