/*
 *  DIR.C - dir internal command.
 *
 *
 *  History:
 *
 *    01/29/97 (Tim Norman)
 *        started.
 *
 *    06/13/97 (Tim Norman)
 *      Fixed code.
 *
 *    07/12/97 (Tim Norman)
 *        Fixed bug that caused the root directory to be unlistable
 *
 *    07/12/97 (Marc Desrochers)
 *        Changed to use maxx, maxy instead of findxy()
 *
 *    06/08/98 (Rob Lake)
 *        Added compatibility for /w in dir
 *
 *    06/09/98 (Rob Lake)
 *        Compatibility for dir/s started
 *        Tested that program finds directories off root fine
 *
 *    06/10/98 (Rob Lake)
 *        do_recurse saves the cwd and also stores it in Root
 *        build_tree adds the cwd to the beginning of its' entries
 *        Program runs fine, added print_tree -- works fine.. as EXE,
 *        program won't work properly as COM.
 *
 *    06/11/98 (Rob Lake)
 *        Found problem that caused COM not to work
 *
 *    06/12/98 (Rob Lake)
 *        debugged...
 *        added free mem routine
 *
 *    06/13/98 (Rob Lake)
 *        debugged the free mem routine
 *        debugged whole thing some more
 *        Notes:
 *        ReadDir stores Root name and _Read_Dir does the hard work
 *        PrintDir prints Root and _Print_Dir does the hard work
 *        KillDir kills Root _after_ _Kill_Dir does the hard work
 *        Integrated program into DIR.C(this file) and made some same
 *        changes throughout
 *
 *    06/14/98 (Rob Lake)
 *        Cleaned up code a bit, added comments
 *
 *    06/16/98 (Rob Lake)
 *        Added error checking to my previously added routines
 *
 *    06/17/98 (Rob Lake)
 *        Rewrote recursive functions, again! Most other recursive
 *        functions are now obsolete -- ReadDir, PrintDir, _Print_Dir,
 *        KillDir and _Kill_Dir.  do_recurse does what PrintDir did
 *        and _Read_Dir did what it did before along with what _Print_Dir
 *        did.  Makes /s a lot faster!
 *        Reports 2 more files/dirs that MS-DOS actually reports
 *        when used in root directory(is this because dir defaults
 *        to look for read only files?)
 *        Added support for /b, /a and /l
 *        Made error message similar to DOS error messages
 *        Added help screen
 *
 *    06/20/98 (Rob Lake)
 *        Added check for /-(switch) to turn off previously defined
 *        switches.
 *        Added ability to check for DIRCMD in environment and
 *        process it
 *
 *    06/21/98 (Rob Lake)
 *        Fixed up /B
 *        Now can dir *.ext/X, no spaces!
 *
 *    06/29/98 (Rob Lake)
 *        error message now found in command.h
 *
 *    07/08/1998 (John P. Price)
 *        removed extra returns; closer to MSDOS
 *        fixed wide display so that an extra return is not displayed
 *        when there is five filenames in the last line.
 *
 *    07/12/98 (Rob Lake)
 *        Changed error messages
 *
 *    27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
 *        added config.h include
 *
 *
 *    04-Dec-1998 (Eric Kohl)
 *        Converted source code to Win32, except recursive dir ("dir /s").
 *
 *    10-Dec-1998 (Eric Kohl)
 *        Fixed recursive dir ("dir /s").
 *
 *    14-Dec-1998 (Eric Kohl)
 *        Converted to Win32 directory functions and
 *        fixed some output bugs. There are still some more ;)
 *
 *    10-Jan-1999 (Eric Kohl)
 *        Added "/N" and "/4" options, "/O" is a dummy.
 *        Added locale support.
 *
 *    20-Jan-1999 (Eric Kohl)
 *        Redirection safe!
 *
 *    01-Mar-1999 (Eric Kohl)
 *        Replaced all runtime io functions by their Win32 counterparts.
 *
 *    23-Feb-2001 (Carl Nettelblad <cnettel@hem.passagen.se>)
 *        dir /s now works in deeper trees
 *
 *    28-Jan-2004 (Michael Fritscher <michael@fritscher.net>)
 *        Fix for /p, so it is working under Windows in GUI-mode, too.
 *
 *    30-Apr-2004 (Filip Navara <xnavara@volny.cz>)
 *        Fix /w to print long names.
 *
 *    27-Feb-2005 (Konstantinos Paliouras <squarious@gmail.com>)
 *        Implemented all the switches that were missing, and made
 *        the ros dir very similar to windows dir. Major part of
 *        the code is rewritten. /p is removed, to be rewriten in
 *        the main cmd code.
 *
 *    1-Jul-2004 (Brandon Turner <turnerb7@msu.edu>)
 *        Added /p back in using ConOutPrintfPaging
 *
 *    3-feb-2007 (Paolo Devoti devotip at gmail)
 *        Removed variables formerly in use to handle pagination
 *        Pagination belongs to ConOutPrintfPaging
 *        Removed already commented out code of old pagination
