Constify command_line_input
This changes command_line_input to return a "const char *", which is
appropriate because the memory is owned by command_line_input. Then
it fixes up the users.
I looked at making command_line_input transfer ownership to its caller
instead, but this is complicated due to the way read_next_line is
called, so I decided against it.
Tested by rebuilding.
