Sigh... I've tried to filter out cases where licensecheck latches on lines 
containing "(c)" like the following one:

 (c)**b <= a and (c+1)**b > a

The line you've shown was seen as garbage and removed because it begins with a 
non-alphanumeric char.

I'll update the cleanup_copyright function in Software::Copyright::Statement 
to cope with this case.

All the best
