OK, I'll take this into account.

But this situation should probably be make more clear in the docs.  Currently,
gitrepository-layout.txt describes refs/replace/ (and shallow) by reference to grafts,
and those are not marked as discouraged-use or anything.

And we may still want the bug fixed, or would we just list it as a known bug ?
At least it does not seem to occur with "replace" refs:

git-test$ rm .git/info/grafts 
git-test$ echo "fake merge" | git commit-tree master^{tree} -p master^ -p maint
b821b2aa00973a47936d7cd25c9a5978b1c839c6
git-test$ git replace master b821b2aa00973a47936d7cd25c9a5978b1c839c6
git-test$ git push origin maint
...
   50b03b0..79211fe  maint -> maint
