Description

When attempting to use an alternate line separator for Throwable stack lines, it seems impossible to use special characters like \t \r \n or anything else.  It also seems impossible to use variable references so one cannot use ${sys:line.separator} as well as other characters.

In the case of simple uses of \t \r \n or anything else are converted to plain text, actually resulting in "\t" in the output.

%-5level - %d{yyyy.MM.dd hh:mm:ss zzz} [%t @ %logger{1}] - %msg%n%ex{separator(\r\n\t)}%n

 If there's a way to do this, it isn't clear in the documentation.
