It looks like regenerate.sh was renamed to post_update.sh in this Gerrit


This change is commit 7cc7771c12. It's a merge commit, which seems to be
affecting git somehow. I found the CL by hand using gitk. "git log --
regenerate.sh" shows nothing, but "git log -- post_update.sh" finds this
merge commit.

"git show 7cc7771c12" reports this for the rename:

diff --cc post_update.sh
index 689a482a,00000000..689a482a
mode 100755,000000..100755
--- a/post_update.sh
+++ b/post_update.sh

"git log 7cc7771c12 -- regenerate.sh" shows nothing.

"git log 7cc7771c12 --follow -- regenerate.sh" shows 3 old commits.

"git log 7cc7771c12~1 -- regenerate.sh" shows the same 3 old commits.
