Evaluating

    (with-temp-buffer
      (setq default-directory "/no/such/dir")
      (get-free-disk-space "/tmp"))

gets an error

    (file-error "Setting current directory" "no such file or directory" 
"/no/such/dir")

where I hoped it wouldn't care about default-directory, only the given
directory argument.  Perhaps a let-bind per below.

I don't think there's any chance to make get-free-disk-space to work on
remote files without major surgery (it currently returns nil immediately
if the file is remote).

I've checked in a modified version of Kevin's patch, which sets
default-directory to "~/" rather than "/", but only if the existing
default-directory is not usable.
