From: Hannes Reinecke <hare@xxxxxxx> libreadline changed the license to be incompatible with multipath-tools usage, so replace it with a simple getline(). mwilck: Make this the default option via Makefile.inc; it is used if READLINE is unset. Compiling with READLINE=libreadline or READLINE=libedit remains possible.
