textbox.c, mixer_display.c:
- Replaced manual line drawing code `for (...) mvwaddch(...)` by the
functions `mvwhline/mvwvline` provided by standard curses
card_select.c, proc_files.c:
- Moved duplicate code in the create() functions to menu_widget_create()
in menu_widget.c
card_select.c:
- Removed redundant calls to sprintf()
device_name.c:
- Combined multiple calls to form_opts_off()
- Recognize ASCII DEL (127) as backspace
widget.c:
- Uncommented code for setting a dummy key handler (all existing
widgets do provide a key handling function)
