Thanks for the report.  If you want 'sum' to output the file name, even 
for one file, then use 'sum --sysv' (or sum -s), although that alters 
the output to strip leading zeroes and use slightly different spacing:

$ sum a
00000     0 a
$ sum -s a
0 0 a

Since this feature is already implemented, I'm closing out this bug report.
