[bug-obsolete-packages] 'comm' command -- bug

[Roy Fulbright]

The 'comm' command has a bug.
If the first line of the two files to be compared are not equal, none of the lines are displayed as equal.
 
Example:
When 'comm' is run against good-file1 and good-file2, lines with a, b, and c are displayed as equal.
When 'comm' is run against bad-file1 and bad-file2, no lines are displayed as equal, because the first lines are not equal.
 
==> good-file1 <==
a
b
c
x

==> good-file2 <==
a
b
c
y

==> bad-file1 <==
x
a
b
c

==> bad-file2 <==
y
a
b
c
