Merge branch 'en/status-multiple-renames-to-the-same-target-fix'

The code in "git status" sometimes hit an assertion failure.  This

used for the first run, which has been corrected.

* en/status-multiple-renames-to-the-same-target-fix:
commit: fix erroneous BUG, 'multiple renames on the same target? how?'
