Ruby

If IRB shows a backtrace that gets truncated because of back_trace_limit, the last line of the backtrace does not end with a newline.

Steps to reproduce:

$ irb -f --back-trace-limit 1 irb(main):001:0> foo 

Actual output:

NameError: undefined local variable or method `foo' for main:Object Did you mean? fork	from (irb):1	from /Users/stefan/.rbenv/versions/2.3.0/bin/irb:11:in `<main>'irb(main):002:0> 

Expected output:

NameError: undefined local variable or method `foo' for main:Object Did you mean? fork	from (irb):1	from /Users/stefan/.rbenv/versions/2.3.0/bin/irb:11:in `<main>' irb(main):002:0> 

Tested with Ruby 2.3.0, but this seems to affect older versions as well.
