>Description:
Using multiple "no"-style file system exclusions doesn't work. Per the man
page, I would expect:
df -t nonull,noprocfs
to exclude all nullfs and all procfs file systems, but it only excludes the first in the list.

The no is only valid at the beginning and negates all of them, as documented:
The list of filesystem types can be prefixed with ``no'' to
specify the filesystem types for which action should not be taken.

Shouldn't it at least warn if it sees another no, then?
(I suppose this would break if someone came up with something called
notfs or nopefs... but it probably does already, and it ought to be
checking the list of known fs types and warning about nonexistent
ones.)
