* lib/stdio/lib_fgets.c: The old fgets includes some terminal related
functionality: It handles VT-100 commands, includes a command line editor
and echo characters back to the terminal. This old, overloaded fgets()
was renamed readline() and moved to apps/system/readline. The version
of fgets() in lib/stdio was them simplified and stripped down so that it
*only* gets a string -- as its description implies.
