Subject: Make "fsck-cache" print out all the root commits it finds.
X-Git-Tag: v0.99~933
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=16d4d1ba6c1de7a414a6826eb6f363d4b20345bf;p=git.git

Make "fsck-cache" print out all the root commits it finds.

Once I do the reference tracking, I'll also make it print out all the
HEAD commits it finds, which is even more interesting.
