What about using the already existing commands below (assuming Vim version 6.2 or later)?
let s:save_isk = &l:isk try setl isk&vim " or to whatever value is desired … … … finally let &l:isk = s:save_isk endtry IMHO authors who won't bother saving and restoring the option won't use your new command either, especially since it will have to be bracketed by if exists() in all third-party syntax scripts, to guard against the possibility of running on a Vim compiled without the patch.
