mergeFromTo conflicts not detected in case of autostash

[paztis]

When --autostash option is enable, conflict are displayed in the log after the merge success.

If I've a non commited file A added locally, and the same in master, then do

git merge origin master --autostash

result is

Updating 67e11a8..0bce1f4
Created autostash: de49df9
Fast-forward
 action/action-test-1.json | 1 +
 1 file changed, 1 insertion(+)
 create mode 100644 action/action-test-1.json
Applying autostash resulted in conflicts.
Your changes are safe in the stash.
You can run "git stash pop" or "git stash drop" at any time.

but the mergeResult in SimpleGit is success.

If I ask simpleGit.status(), conflit is well displayed.

I thing this use case is not managed in the log parser.
