[PATCH 6/7] rebase -p: don't request --left-right only to ignore left side

[Martin von Zweigbergk <martin.von.zweigbergk@gmail.com>]

While generating the todo file, rebase -p calls 'git rev-list
--left-right a...b' (with 'a' equal to $upstream or $onto and 'b'
equal to $orig_head) and its output is piped through 'sed -n
"s/^>//p"', making it equivalent to 'git rev-list --right-only
a...b'. Change the invocation to exactly that.

(One could alternatively change it to 'git rev-list a..b', which would
be even simpler, if it wasn't for the fact that we already have the
revision range expression in a variable.)
