Sorry, I was not clear enough in my previous mails (although I did send a
corrective email to fix this): there is not need to have two hooks, you
should create the two directories in the same hook.

No need to resend, the comitter can do the change, hopefully! ;-)

Thank you! :-)

Regards,
Yann E. MORIN.

Thanks, patch applied, after doing the change suggested by Yann (use
only one hook to create the missing directories).
