* cygpath.cc (main): Add option l to support conversion to Windows long file names. Refactured code for capital options. Support of options from file for capital options. (dowin): New function. Refactured from main. (doit): Call long path conversion. (get_long_name): New function. (get_long_paths): New function. (get_long_path_name_w32impl): New function. Reimplementation of Windows API function GetLongPathName (only 98/Me/2000/XP or higher). (get_short_name): Call GetShortPathName only once. (get_short_paths): Fix calculating buffer size. * utils.sgml: Update cygpath section for l option.
