Re: git-rev-list: proper lazy reachability

Hello Junio, I pull the REMOTE_HEAD including objects but don't merge. After that I run:

system("git-rev-tree HEAD REMOTE_HEAD | sed -e 's/^[0-9]* //' | git-diff-tree --stdin -v ");

for bitkeeper I used the merge base approach (but at that time I only knew that this gives me any deltas in the current tree not in the remote tree, but didn't know how it worked).

bkparentdiff is aliased to `bk rset -hr`bk repogca`,+ | grep -v ^BitKeeper | bk gnupatch -du -e -h -T'
