Now after thinking about it a bit more, I actually have a moderate
preference to doing it the way your patches do.  With programatic
%(if)%(else)%(end) support we acquired recently, the fallback can be
coded in the --format=... language if the user wanted to using the
"internal fallbacks, explicit==0, are ignored" behaviour that are
implemented by these two patches.  The reverse is not true.

I think the remaining points from my reviews are:

 - It would be better to compute precomputable stuff when used atoms
   are parsed, instead of running starts_with() in these functions;

 - We want to make sure there is no existing multi-word modifiers
   (in which case we can safely declare "multi-word" is the way we
   spell them from now on).  Or if there are existing ones, they
   already spell themselves as "multi-word".

   I have nothing against "remote-name"; I just want to make sure we
   are not making things inconsistent.  If there are only few (but
   non zero number of) multi-word modifiers that are not spelled
   "multi-word", as long as they are only few and their spelling are
   inferiour (e.g. concatenatedwords is much worse than
   concatenated-words), we could still declare "multi-word" is the
   right way to spell them going forward, declare that we will give
   them synonyms and deprecate the bad spelling out over time, and
   leave that plan as #leftover bits thing (i.e. not doing the
   deprecation of these other modifiers as part of this series.

   The only thing I want to happen in the scope of _this_ series, as
   due diligence, is to make sure we are happy with "multi-word",
   and also to know if we need a follow-up work (just yes/no,
   possibly with plans, but no actual work yet).
