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.
