cc65/libsrc/atari/sysrmdir.s
Christian Groessler da65866e24 Atari: add new function '_is_cmdline_dos()' and some other small changes.
- use this function instead of directly looking at _dos_type in the included
  targetutil and test programs
- fixes/improvements to the Atari runtime library regarding the recently
  changed _dos_type values
- libsrc/atari/targetutil/w2cas.c: exit if no filename was entered
- add documentation for the new function
