Hm, I wonder why string-substitute and string-substitute*
look so different; one uses an internal concatenate the other
uses ##sys#fragments->string.
The other note I found: even if I put only one pair in smap,
the time string-substitute* took is double the time
string-substitute took.
The count string-search-positions that I counted
was also twice with string-substitute*.

Does this help anyting?
