Hmm. My guess is that the new "check for connectivity when leaving detached HEAD" test is polluting the commit flags for the ahead/behind test.

[bisect bisect bisect]

Yep, it bisects to 8e2dc6a (commit: give final warning when reattaching HEAD to leave commits behind, 2011-02-18). We probably need to clean the uninteresting flags between the two traversals.
