Revision f74bbc8dd2637498bc07132ae6bfa6d1b88dafb0 authored by Jeff King on 21 February 2018, 23:27:24 UTC, committed by Junio C Hamano on 22 February 2018, 20:15:25 UTC
This was an undocumented debugging aid that does not seem to have come in handy in the past decade, judging from its lack of mentions on the mailing list. Let's drop it in the name of simplicity. This is morally a revert of 3131b71301 (Add "--show-all" revision walker flag for debugging, 2008-02-09), but note that I did leave in the mapping of UNINTERESTING to "^" in get_revision_mark(). I don't think this would be possible to trigger with the current code, but it's the only sensible marker. We'll skip the usual deprecation period because this was explicitly a debugging aid that was never documented.
