- * 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.
- *
- *  Ben Lindstrom <mouring@eviladmin.org> 09/27/00 for OpenSSH
- *    Welcome to the world of %lld and %qd support.  With other
- *    long long support.  This is needed for sftp-server to work
- *    right.
- *
- *  Ben Lindstrom <mouring@eviladmin.org> 02/12/01 for OpenSSH
- *    Removed all hint of VARARGS stuff and banished it to the void,
- *    and did a bit of KNF style work to make things a bit more
- *    acceptable.  Consider stealing from mutt or enlightenment.
