What do you mean?  It says it right there:

   With no options, `comm' produces three-column output.  Column one
contains lines unique to FILE1, column two contains lines unique to
FILE2, and column three contains lines common to both files.  Columns
are separated by a single TAB character.

Of course this is the texinfo documentation, viewable with "info
coreutils 'comm invocation'".  If you're referring to the man page, that
is just an autogenerated summary which is the same as the "comm --help"
information, which is meant as a brief summary, not full documentation. 
So, in other words, use the info documentation.  If you don't like the
'info' program there are numerous alternatives, the easiest of which is
HTML:
<http://www.gnu.org/software/coreutils/manual/html_node/comm-invocation.html>.

The ability to specify something other than TAB would probably be a
useful feature to have, though.
