dfree example

[Harald Koenig]

Hello SAMBA,

almost exactly 3 years ago I send you this report/patch for problems
with your example for "dfree"
     
     http://lists.samba.org/archive/samba-technical/2003-October/032414.html


now I was asked/bitten again by this problem and realize that it never was
changed in samba:

	# grep -r 'tail -1' samba-3.0.26a/docs
	samba-3.0.26a/docs/htmldocs/manpages/smb.conf.5.html:df $1 | tail -1 | awk '{print $2" "$4}'
	samba-3.0.26a/docs/htmldocs/manpages/smb.conf.5.html:/usr/bin/df -k $1 | tail -1 | awk '{print $3" "$5}'
	samba-3.0.26a/docs/htmldocs/using_samba/ch11.html:df $1 | tail -1 | awk '{print $2&quot; &quot;$4}'</pre></blockquote>
	samba-3.0.26a/docs/htmldocs/using_samba/ch11.html:/usr/bin/df $1 | tail -1 | awk '{print $3&quot; &quot;$5}'</pre></blockquote>
	samba-3.0.26a/docs/manpages/smb.conf.5:df $1 | tail -1 | awk '{print $2" "$4}'
	samba-3.0.26a/docs/manpages/smb.conf.5:/usr/bin/df -k $1 | tail -1 | awk '{print $3" "$5}'


so I try again....
