Function ext_cmd_getlin_hook

win/tty/getline.c:271–285

* Implement extended command completion by using this hook into * tty_getlin. Check the characters already typed, if they uniquely * identify an extended command, expand the string to the whole * command. * * Return TRUE if we've extended the string at base. Otherwise return FALSE. * Assumptions: * * + we don't change the characters that are already in base * + base has enough

 *      + base has enough room to hold our string
