Hello Derek,

thank you very much for taking care about this.

I haven't seen the patch; and won't see before you commit, as I'll be
offline until Jun 21.

That's why I add some comments now, though you probably know most of
them:
- We need to document also AS_LITERAL_IF and m4_fatal
  (And you could also document m4_warning, when you are at it.)
- we have to document also the fact that AS_TR_SH & AS_TR_CPP expand
  to literal variable (symbol) name, if their argument is a literal

A cheeky closing note:
Bruno, your code also uses undocumented macros: `define', `undefine'
and `translit'.  Please note that the manual states that they are
_moved_ into the m4_ pseudo-namespace.
And IMHO these will never be documented, they are only for backward
compatibility.  ;-)

Have a nice day,
        Stepan
