+I found the culprit: largefiles.
+
+I use
+```
+* annex.largefiles=mimeencoding=binary
+```
+
+in my documents repo because I need to efficiently store lots of text and diff, merge etc. properly.
+
+Here are the revised repro steps:
+
+```
+git init test
+cd test
+git annex init
+git config annex.delayadd 5
+echo '* annex.largefiles=mimeencoding=binary' > .gitattributes
+git add .
+git commit -m \"gitattributes: largefiles\"
+git annex assistant
+echo `date` > test
+git log --patch
+```
+
+The date of the commit should be the date in the file +5s.
