I am not sure what you are saying.

If it is "I do not want color-words on by default for LaTeX", then I
agree. I meant merely that _if_ color-words is enabled, the word
boundaries would be taken from the diff driver config (just like we do
for matching the funcname header).

If it is "I want to specify the color-words boundary on a per-run basis
rather than a per-file basis", then I want the opposite. However, there
is no reason that both cannot be supported (with command line or
environment taking precedence over what's in the config).
