Input > does not recognize EOF

[madkins23]

There seems to be no way to enter an EOF in the Input > field. Normally I would use <ctrl>-D (on Linux) but that isn't recognized. Testing code that reads from *standard-input* until EOF is difficult.

Test with:

(loop for line = (read-line *standard-input* nil nil)
      while line
      do (print line))

It is possible to kill the thread. That doesn't immediately remove the Input > field, but the next time anything is entered there it goes away. In a case where the code is waiting for EOF before doing actual work killing the thread won't help.
