[PATCH] git-revert with conflicts to behave as git-merge with conflicts

[Luben Tuikov <ltuikov@xxxxxxxxx>]

In a busy project, reverting a commit almost always results
in a conflict between one or more files (depending on the
commit being reverted).  It is useful to record this
conflict in the commit-to-be message of the resulting commit
(after the resolve).  The process now becomes:

git-revert <SHA-1>
<git complains and prints failed automatic>
<user manually resolves>
git-update-index <resolved files>
git-commit -s

And the commit message is now a merge of the revert commit
message and the conflict commit message, giving the user a
chance to edit it or add more information:
---cut---
Revert "title of reverted commit"

This reverts commit <SHA-1>

Conflicts:

    <filename>
    ...
---cut---
