This is a definite improvement.

I like the lazyness between string & numeric forms, and for sorting, that 
is what was needed doing to have something clean.

Applied on head, it works for me.

While testing the patch I found a minor preexisting (mine...) bug: when 
string-scanning doubles, whether the whole string is consumed or not is 
not checked. This means that -D x=0one is interpreted as double 0.

I came up with the attached check, but maybe there is a cleaner way to do 
that.
