import: fix parent selection when importing merges With "wp1" and "wp2" the current working directory parents, "p1" and "p2" the patch parents and "parents" the resulting commit parents, the current behaviour is: --bypass --exact p2 parents 0 0 0 [wp1, wp2] 0 0 1 [wp1, wp2]/buggy 0 1 0 [p1] 0 1 1 [p1, p2] 1 0 0 [wp1, wp2] 1 0 1 [p1, p2] 1 1 0 [p1] 1 1 1 [p1, p2] The original behaviour before f53dc0787424 was: --bypass --exact p2 parents 0 0 0 [wp1, wp2] 0 0 1 if p1 == wp1 then [p1, p2] otherwise [wp1, wp2] 0 1 0 [p1] 0 1 1 [p1, p2] This patch restores the previous behaviour when --bypass is not set, and align --bypass behaviour when --exact is not set with merge diffs.

graft: disallow grafting grafted csets in specific situations (issue3091) In particular, we do not allow: - grafting an already grafted cset onto its original branch - grafting already grafted csets with the same origin onto each other

graft: use revs to make tests more readable

graft: preserve original source in subsequent grafts

makedate: wrong timezone offset if DST rules changed this year (issue2511) Python's time module sets timezone and altzone based on UTC offsets of two dates: first and middle day of the current year. This approach doesn't work on a year when DST rules change. For example Russia abandoned winter time this year, so the correct UTC offset should be +4 now, but time.timezone returns 3 hours difference because that's what it was on 01.01.2011.
