[PATCH v2 0/2] revision.c: implement --reverse=before for walks

[Mirko Faina <mroik@delayed.space>]

Since v1 I've:
	* removed the non stuck form for the --reverse option
	* --reverse with no argument now flips "no reverse -> reverse
	  after", "reverse after -> no reverse" and "reverse before ->
	  no reverse"
	* implemented a window to reduce memory usage when
	  --reverse=before with --max-count=<n>
	* updated the docs to highlight the peculiarities of --reverse
	  when it's specified multiple times
