This removes the code coming from git-rebase--interactive.sh that is not
needed by preserve-merges, and changes the header comment accordingly.
In a following commit, the -p code from git-rebase--interactive.sh will
be stripped out. As preserve-merges’ successor is already in the works,
this will be the only script to be converted.
This also seems to fix a bug where a failure in
`pick_one_preserving_merges()` would fallback to the non-preserve-merges
`pick_one()`.

This duplicates git-rebase--interactive.sh to
git-rebase--preserve-merges.sh. This is done to split -p from -i. No
modifications are made to this file here, but any code that is not used
by -p will be stripped in the next commit.
