As Alexander has already pointed out, the issue is in the Debian 
packaging. It was fixed in version 1.9, but you are using an old version 
of ed.

'red' was made a shell script executing "ed --restricted" in version 1.5 
(2010-08-30), following the GNU Coding Standards:

http://www.gnu.org/prep/standards/html_node/User-Interfaces.html#User-Interfaces

"Please don't make the behavior of a utility depend on the name used to 
invoke it. It is useful sometimes to make a link to a utility with a 
different name, and that should not change what it does.

Instead, use a run time option or a compilation switch or both to select 
among the alternate behaviors. You can also build two versions of the 
program, with different names and different default behaviors."


Best regards,
Antonio.
