The "Conflicts:" part is totally irrelevant.  Please remove.

Why isn't it "pull --all"?

Where did "push_all" go?

"grep -o" is not even in POSIX. Besides, what is this trying to parse? Is it expected to match lines like

	path.subtree=trash

with this, or is it more like you only want something like this:

	subtree.over/there.path=foo

in which case you would want to read with something like

	sed -n -e 's/^subtree\...*\.path=\(.*\)/\1/p'

instead (modulo the usual caveat on $IFS whitespaces in path)?

I'd stop looking at this series myself at this step for now.
