where FORMAT_END is null, take just one pass over FORMAT, not two.

allocate a copy of the format FMTCPY; instead, use a small fixed-size
array FMTSTAR, and use '*' in that array to represent width and
precision, passing them as separate int arguments. Use eassume to
pacify GCC in switch statements.
