diff: recurse into nested submodules for inline diff
When fd47ae6a5b (diff: teach diff to display submodule difference with an
inline diff, 2016-08-31) was introduced, we did not think of recursing
into nested submodules.
When showing the inline diff for submodules, automatically recurse
into nested submodules as well with inline submodule diffs.
