In fact, there is a Topcat way to store the description TCOMMnn, nn being the 
column number. But as it is not in the standard, it is not taken into accound 
by astropy.  The problem is that when you open a table with astropy and add a 
column, when you save the table an open it again with Topcat the column 
descriptions are wrong from the inserted column on, because astropy kept the 
TCOMM keywords.

Strictly speaking, it is not a bug in astropy as it deals with the TCOMM 
keywords as any other keyword.  What people think about this?
