   If ls_mode is LS_LONG_FORMAT,
   the long format is the default regardless of the

      // BUG: CMD.EXE mangles the command line args from the OEM code page
      // to the ANSI code page, breaking console output.
      // The BUG still exists as of Vista.
      //
      // Example:
      //
      // FOO.EXE "ALT+130" (OEM e-accent) on keyboard input to CMD.EXE
      // comes out as argv "ALT+0233" (ANSI e-accent)
      //
      // As a test to prove that argv is mangled I wrote a trivial console
      // program that puts(argv[1]).  With keyboard input ALT+130 (OEM)
      // -- showing a nice e-accent on the console for the command line --
      // it instead prints ALT+0233 (ANSI), which looks like junk on stdout.
      //
      // This is due to a BUG in CMD.EXE, probably due to failure to
      // call SetFileApisToOem() before invoking CreateProcess("FOO.EXE",argv)
      // to create the console process.   It ought to check the SUBSYSTEM
      // bytes in the executable header and then set the code page 
      // appropriately.
      //
      // BUGFIX: De-mangle the argv strings in-place from ANSI back to OEM.
      //
      // Microsoft's own command-line fileutils (XCOPY.EXE, ATTRIB.EXE, etc)
      // use the undocumented ULIB.DLL to work around the CMD.EXE bug.  ULIB
      // knows how to de-mangle argv from ANSI back to the original OEM.
      // It knows how to correct the OEM Locale and MBCP mode (see above).
      //
      // ** A plea to Microsoft: Please document ULIB.DLL.  It would be
      // extremely helpful for 3rd party developers who need to create 
      // console-mode utilities that support international languages. **

By default, color is not used to distinguish types of files.  This is\n\
equivalent to using --color=none.  Using the --color option without an\n\
argument is equivalent to --color=always.  When using --color=auto, color\n\
codes are generated only if the output is a display console.\n\
\n\
Use the environment variable " LS_PREFIX "_OPTIONS to set default options.\n\
Example: -bhAC --more --color=auto --recent --streams\n\
