Bug#537838: [checks/manpages] .ig EOC -> .EOC warned as missing macro
a fancy man page has this little section here (actually many of these sections and the package (torque) has many man pages, hence the bug is not minor) :
..if !\n(Pb .ig Ig
..if \n(Pb .ig Ig
which means that the block may be skipped.
lintian does not get it but warns about .Ig being an undefined macro - it is not. It is the end of the comment.
