James Peach commented on TS-1042:
---------------------------------
To be honest, it's mostly from habit. However "%*.*s" prints exactly the number
of bytes whereas "%.*s" prints up to the number of bytes. In this particular
case we know the number of bytes and we want to print all of them so "%*.*s"
seems like the right choice. But "%.*s" will fix the bug just as well.
