I looked at the df code because I was intensely curious how this could
happen. It obtains the list of mounts using a NOWAIT flag, and NFS mount
info may not be available immediately so it doesn't get included in the
field width calculations. Then later it re-gets the list of mounts using a
WAIT flag (unless you used -n on the command line) so this time it has the
info from NFS filesystems, but it doesn't recalculate the field widths. The
following patch should fix it without breaking other behaviors, I belive.
