[Buildroot] CTRL+C in menuconfig deletes .config

i dont know why the menuconfig target has this logic:
    @if ! $(COMMON_CONFIG_ENV) $< $(CONFIG_CONFIG_IN); then \
        test -f $(CONFIG_DIR)/.config.cmd || rm -f $(CONFIG_DIR)/.config; \

but it causes severely undesirable behavior.  if i do:
	make menuconfig
	<change some things & save>
	make menuconfig
	<change some things but change my mind and hit CTRL+C>

the build system deletes the .config file.
