OK.  But I'm afraid I don't understand your point.  I get the same 
results whether I use the actual filename as an argument or the 
directory that contains the filename.  I thought that's what you were 
pointing out.  The info for "file" says that 

 "[...] `df' reports on the filesystem containing each argument FILE."

and indeed:

[ofeeley@ars ofeeley]$ df /usr/bin/Mail
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3             14120684   9013132   4390252  68% /
[ofeeley@ars ofeeley]$ df /usr/bin
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3             14120684   9013132   4390252  68% /
