Tony Finch 38281fea3e Fix a performance bug in factor(6).
Check if large factor is prime before applying Pollard's algorithm;
fixes "factor 2147483647111311".  Increase base if p-1 algorithm
reaches 1; fixes "factor 99999999999991".

Testcases from David A Bagley <bagleyd@tux.org>.
Fixes from Joseph Myers <jsm@NetBSD.org>.
Problem rediscovered by an attempt to factor my phone number.

A few other incidental fixes: correct a couple of factually incorrect
comments; use ident string macros; move from 4-clause to 3-clause
