I would like this. Sometimes I manually call `i' on specific dirs and
get tired of needing to do C-u C-SPC to get back. Double tapping `i'
would be much more convenient. Maybe, maybe maybe maybe, should it
also step one line down from the original dir line when jumping back,
but that depends on how you use it I guess, it would fit my way of
working with dirs in Dired. It has the disadvantage however that you
cannot go back to the inserted dir again by tapping `i' for a third
time.
