* 4397_winput_api_fixes:
  Clarify checks of input line content returned from quick dialog.
  (input_get_ctext): mew API.
  (input_destroy): remove check if WInput object is NULL. This object must exist.
  WInput: make one-line APIs inline.
  (input_is_empty): remove checks. WInput object must exist.
  Ticket #4397: sort in editor without arguments stopped working.
