Fix quote around macro argument
In m4/curses.m4, line 134, the 5th argument passed to AC_NCURSES was surrounded by '"' instead of '[' and ']'. Because of that, the expansion of AC_NCURSES in that case would produce the following line inside the configure script (note the repeated double quotes): screen_manager=""ncurses on $withval/include"" That would cause the following error when configure was executed with the "--with-ncurses=dir" argument: ./configure: line 13468: on: command not found Although in the case above the error doesn't actually influence the build process ('screen_manager' isn't used anywhere in the script), trying to execute 'on' might be harmful if it corresponded to an existing command in the user's environment.
