Hi Carl,

Good catch!  The patches LGTM.  (Note: you can use the ‘Co-authored-by’
tag for the second patch, I think it’s a more or less common
convention.)

Speaking of which, could you create an account on Savannah?  That way we
could grant you commit access to make it more convenient for you and so
you can review and apply other people’s patches in your areas of expertise.

Please let me know what your account is, and reply with a message signed
by the key you’ll use to sign commits.  Also please read the ‘HACKING’
file for info on the commit “rules”.

Thanks!

Ludo’.
