mutt's .mutt folders when saving attachments?

[Tim Chown <tjc@xxxxxxxxxxxxxxx>]

Hi,

I didn't get a reply when I asked before, still keen to find out how
to avoid mutt creating/leaving an empty .muttxxxxxx fo9lder in the
directory in which an attachment is saved.   I assume there's some
option to autodelete these folders?
