I tried to reproduce this issue with the following sequence in unstable:
1. apt-get install tomcat7
2. touch /opt/file1
3. ln -s /opt/file1 /etc/tomcat7/file1
4. apt-get remove tomcat7
5. apt-get purge tomcat7
The link was the last remaining element in /etc/tomcat7 and the
/opt/file1 hasn't been removed.
Rafal, could you try again with the version of tomcat7 from testing or
wheezy-backports please? If the issue is still there please detail the
steps to reproduce it and I'll look into it.
