Hello Ethan,

Thanks for the patch set.  Overall the patches look good to me modulo
minor issues that I’ll comment on:

Could you squeeze that on one or two lines?

Please double-check that this is needed.  Usually, but not always,
projects that use Autoconf & co. provide self-contained tarballs such
that one doesn’t need to run ./autogen.sh.

Could you improve the synopsis and description according to the
guidelines at

Please take a look at

haven’t already.

Could you send updated patches?

Thanks in advance!
