them from being so easily run into ``rm -rf /'', ``rm -rf *''

The previous version would just step to March 31 and rely on mktime(3)

to users and caused pain to shell script writers.

Note that the mount point which is not accessible shows
up as the previous file system that was printed. The reason
for this is that df -t will call statfs(2) on the pathname
supplied by getfsstat(2).
This is done to refresh the file system statistics in the
event that a previous file system had a long delay in
providing its stats.
This change affects the df utility in the following ways:
o Teach df has to deal with statfs(2) failing. If statfs(2)
fails, fall back on the possibly stale stats provided by
the initial call to getfsstat(2).
o Print a warning that the fs stats could possibly be stale
o Modify the man page and document this new behavior
as a bug.
