is useful even though a similar effect is achievable with sort(1),
since the latter doesn't work in combination with -h. This option is
also present in NetBSD, OpenBSD, and GNU fileutils, so there's clearly
a demand for it.

work as expected when they have a "shebang line" of:
#!/bin/sh -- # -*- perl -*- -p
This specific line is recommended in some perl documentation, and I think
I've seen similar lines in documentation for ruby and python. Those
write-ups expect `sh' to ignore everything after the '--' if the first
thing after the '--' is a '#'. See chapter 19, "The Command-Line Interface"
in 3rd edition of "Programming Perl", for some discussion of why perl
recommends using this line in some circumstances.
The above line does work on solaris, irix and aix (as three data points),
and it used to work on FreeBSD by means of a similar patch to execve().
However, that change to execve() effected *all* shells (which caused
other problems), and that processing was recently removed.

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.
