In Wanderlust, the file name (represented by message number) for the
draft is decided when buffer is made. But Wanderlust updates it to
make the latest saved draft have largest number. So, Wanderlust needs
to check and modify the file name at saving for the case that another
draft is saved while editing the draft. Setting buffer-file-name to
existing directory could avoid the present problem, but I think that
is very ad hoc.

Thank you for pointing it out. It seems that Emacs does not expect
buffer-file-name is modified while hook functions. Additionally, I
noticed that Wanderlust could save draft into non-local file, i.e.
remote imap4 server. If basic-save-buffer really does not support
such cases, Wanderlust would need the workaround or to have own draft
