       mailfs: allow spaces in box name
       
       Mail services (such as Google Mail) will often have
       directories with names that contain spaces. Acme
       does not support spaces in window names. So, replace
       spaces in mail directory names with the Unicode
       character for visible space.
       
       The code is a bit of an over-approximation and
       generally non-optimal.
