2.15.1 - merge with submodule output issue

Dear git,

I use since few weeks now git 2.15.1.

I did few trials but please find here my outputs.

To reproduce: Use a top module git which include a submodule First step: from a work area, I changed selected version of submodule in master branch. Then git add + git commit + git push  A new commit on master branch has been published on my origin repository with the version v1.2 of submodule

Second step: in my second workarea, I created a user branch mybranch, then selected another release of submodule I added the update and then commit in mybranch.  A new commit with release v2.0 of submodule is in my last SHA1 of mybranch

Last step: in the second workarea, in mybranch, I first run ‘git fetch’ and then ‘git merge origin/master’ I got a CONFLICT message of course due to the 2 different versions of submodule. Here the message: warning: Failed to merge submodule submodule (commits don't follow merge-base) Auto-merging submodule CONFLICT (submodule): Merge conflict in submodule Automatic merge failed; fix conflicts and then commit the result.

Now I thought that the command ‘git submodule’ provided an output with both versions of modules (local and remote). But this is not the case in my environment: [15:20:10] $ git submodule status U0000000000000000000000000000000000000000 submodule

And when I run the mergetool command I have this output:
[14:54:41] $ git mergetool 
Merging: 
submodule 
Submodule merge conflict for 'submodule': 
  {local}: submodule commit 08f86f2404d9f8f616262971a3127e69f39f9d11 
  {remote}: submodule commit b3dd6fde4f02258b88ad0b2dba6474c126b499f7 
Use (l)ocal or (r)emote, or (a)bort? 

So, it means it’s not usefull to determine which version has to be selected. Is it a bug or perhaps I make something wrong?

It will be usefull if we can hav e this information during git mergetool command like with git describe .

Thanks for your help.
