I'm actually using the John's backtick and I like them alot for
easily escaping WikiWords. But the backtick only works with WikiWords
IRCC, and this is also how I think they should work.
The null-token is more of a general purpose solution, that'll guarantee
to break any pattern. I've thought about using the backtick as a
null-token, but backticks are used in for instance the help text's of
Emacs lisp-files and in Maple files...
In addition, how would you actually print a backtick?
Using [=`=]? I think you'd get other problems doing that.
Maybe an exception could be made for translating '``' into a '`' but I
think that could be confusing. And you still couldn't easily quote for
instance Emacs lisp files.
