     ui_out, and nothing else has been printed yet (both
     M_START_OF_LINE and M_LINE are still 0), we assume
     print_source_lines is starting to print a source line, and thus
     record the line number in M_LINE.  Afterwards, when we see a
     string field named "fullname" being output, we take the fullname
     and the recorded line and show the source line in the TUI's
     source window.  tui_ui_out::do_text() suppresses text output
     until it sees an endline being printed, at which point these
     variables are reset back to 0.  */
