Sorry I missed that message.
The commit log text is a good explanation, and deserves to be
a comment in the code, so I have written a patch in your name
to factor out those two duplicate blocks, also adding your commit
log message as a comment.  Since this commit is in your name,
I would appreciate a careful review and an explicit "ACK" (or
suggestion for correction or improvement) from you before I push it.

I will also add your test in a separate upcoming commit.
