Re: [PATCH v2 0/2] Address recovery failures with directory/file conflicts

This patch series fixes several "recovery" commands that outright fail
or do not fully recover when directory-file conflicts are present.
This includes:
   * git read-tree --reset HEAD
   * git am --skip
   * git am --abort
   * git merge --abort (or git reset --merge)
   * git reset --hard

Changes since v1 (full range-diff below):
  - Make use of test_write_lines, as suggested by Eric.
  - Provide a little more explanation in one of the commit messages, as
    suggested by Junio.

I forgot to mention: there is also an expected failing merge --abort
testcase in en/t7405-recursive-submodule-conflicts (currently in pu),
and the fact that this series does not fix that testcase is known.
For the curious...

This read-index-unmerged series is part of the solution for the
problem highlighted in t7405; in fact, the similarity between
file/directory and submodule/directory conflicts is such that this
patch series does also happen to fix recovery problems for many
submodule/directory conflicts as well.  However, additional work is
needed when the same path is found under both the submodule and the
directory, and the testcase in en/t7405-recursive-submodule-conflicts
is precisely one of those cases that needs additional work.

(This is just a long winded way of saying that this series and
en/t7405-recursive-submodule-conflicts don't conflict or duplicate
each other.)
