 *
 * Usage: timer ncomp nexec nsub
 *	or
 *	timer ncomp nexec nsub regexp string [ answer [ sub ] ]
 *
 * The second form is for timing repetitions of a single test case.
 * The first form's test data is a compiled-in copy of the "tests" file.
 * Ncomp, nexec, nsub are how many times to do each regcomp, regexec,
 * and regsub.  The way to time an operation individually is to do something
 * like "timer 1 50 1".
