Minor fixes.

* mailbox/mailbox.c (_create_mailbox0): Take care not to destroy
url, if creation of the mailbox failed.
(_create_mailbox): Destroy url if unable to create mailbox.

* mailbox/mutil.c (mu_is_proto): Take starting | as a protocol
specification. A kludge.

* include/mailutils/argcv.h: Fix indentation.
