* NEWS: Mention this. * src/remove.h (enum rm_interactive): New ternary type. (struct rm_options) [interactive]: Use it, here -- rather than bool. * src/remove.c (prompt): Reflect type change. * src/mv.c (rm_option_init): Initialize to RMI_NEVER now. * src/rm.c (main): Add a FIXME comment for '-d' option. Adapt to type change of rm_options.interactive. * tests/rm/i-never: New file. Test for the above fix. * tests/rm/Makefile.am (TESTS): Add i-never.
