Make string operator-overload costs match their intuitively equivalent arithmetics.

Replace many by-reference string args with by-value args to work around noise from the reference-cost column.

Use a special arithmetic type for the factor argument of ?*? to match conversion cost of (char*int=int).

Removes cost-function noise of char-arithmetic operators being preferred over their string-concatenation equivalents in the reference-cost column.

Notably, all former Spanish-A and numeric outputs have become ambiguous or been associated with a reproducible bug.
