+ * Original:
+ * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
+ * A bombproof version of doprnt (dopr) included.
+ * Sigh. This sort of thing is always nasty do deal with. Note that
+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length. This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ * Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
+ * This was ugly. It is still ugly. I opted out of floating point
+ * numbers, but the formatter understands just about everything
+ * from the normal C string format, at least as far as I can tell from
+ * the Solaris 2.5 printf(3S) man page.
+ *
+ * Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
+ * Ok, added some minimal floating point support, which means this
+ * probably requires libm on most operating systems. Don't yet
+ * support the exponent (e,E) and sigfig (g,G). Also, fmtint()
+ * was pretty badly broken, it just wasn't being exercised in ways
+ * which showed it, so that's been fixed. Also, formated the code
+ * to mutt conventions, and removed dead code left over from the
+ * original. Also, there is now a builtin-test, just compile with:
+ * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ * and run snprintf for results.
+ *
+ * Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
+ * The PGP code was using unsigned hexadecimal formats.
+ * Unfortunately, unsigned formats simply didn't work.
+ *
+ * Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
+ * The original code assumed that both snprintf() and vsnprintf() were
+ * missing. Some systems only have snprintf() but not vsnprintf(), so
+ * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ * Andrew Tridgell (tridge@samba.org) Oct 1998
+ * fixed handling of %.0f
+ * added test for HAVE_LONG_DOUBLE
+ *
+ * Russ Allbery <rra@stanford.edu> 2000-08-26
+ * fixed return value to comply with C99
+ * fixed handling of snprintf(NULL, ...)
+ *
+ * Hrvoje Niksic <hniksic@arsdigita.com> 2000-11-04
+ * include <config.h> instead of "config.h".
+ * moved TEST_SNPRINTF stuff out of HAVE_SNPRINTF ifdef.
+ * include <stdio.h> for NULL.
+ * added support and test cases for long long.
+ * don't declare argument types to (v)snprintf if stdarg is not used.
+ * use int instead of short int as 2nd arg to va_arg.
