I have several org files that contain simulator command arguments that look
like this:

    +ADTL_ARG+somethingOrOther
or
    /long/path/to/..../somewhere/
or
  _token_to_get_inserted_in_something_

These appear in both headlines and non-headline text. It's pretty
distracting, particularly when i'm trying to put together groups of these
things to build a long command line. Sometimes i have to just switch to
fundamental mode for a while.

Is there a way to inhibit fontification of this kind of thing? It'd be nice
if i could do it on a per-line or per-region basis. Maybe in response to a
tag in the headline? Maybe in response to a property?
