I think Tomas probably knows better.
In particular I am also unsure that 15 really is correct and it
shouldn't rather be 16.
In general I don't get the system behind the match length.
If it is just meant to be the minimal length to make the match
unique it would be better to just change the code to look for the
maximal match (possibly with some threshold and a warning if multiple
equally good matches exist).
