Just it has a sort-of-regression:
(gdb) set args ~
(gdb) show args
Argument list to give program being debugged when it is started is "~".

Argument list to give program being debugged when it is started is "/home/jkratoch".

Therefore please modify also:
  add_setshow_optional_filename_cmd ("args", class_run,

to rather use add_setshow_string_noescape_cmd together with:
  set_cmd_completer (set_result, filename_completer);

It should not affect anything else I think.

Pre-approved with that change.


Thanks,
Jan
