mpv/libmenu/menu_filesel.c
albeu 38a2fa46fd I've juste found a bug which prevent to load a file whose name contain
a quote ('). The menu simply execute a "loadfile '%p'" but when the %p
is replaced by the actual value, quotes in it are not escaped !
Moreover, mp_input_parse_cmd contain some code to unescape strings but
this code was placed after the string was copied in his final buffer.

So this patch correct this issue.
