Re: force "unmerged" for same-file auto-merges

In other words, when two people modify the same file in different places I 
want the automerge results file, but I want the resulting file marked as 
unmerged so the programmer can then run git-mergetool to review the merge 
results.  This also prevents the programmer from running git-commit 
immediately after the automerge without reviewing the merge results.  Can 
"mark automerge of samefile as 'unmerged'" be done in git via config 
settings or command options?

Scenario:  "same-file auto-merge":  when two different people change the 
same file in their separate repos.  Their changes do not conflict in the 
sense that they are changes to the same lines.  However, their changes do 
conflict in the sense that the resulting merged logic is incorrect.

Concern:
The same-file auto-merge results are overlooked (not reviewed) by the 
programmer because there is nothing preventing a git-commit immediately 
after the auto-merge completes.

Desired Solution:
Perform same-file auto-merge and produce auto-merge results, but mark all 
such auto-merged files as "unmerged" so that they must be 
reviewed/resolved before a git-commit.  The "unmerged" status allows 
git-mergetool to be run (e.g. kdiff3) so that the merged lines can be 
reviewed.  In this way, all auto-merged files are reviewed.

Does anyone know if there are configuration and/or command-line options in 
git that can accomplish this in a fairly straightforward manner?  For 
example, something like this:


Example config:
$ cat gitconfig
[merge]
           samefileauto = forceconflict


Example command:
$ git merge -s sameautoforceconflict branchx


Example results:
$ git merge -s sameautoforceconflict branchx
