  interrupt a function via timeouts.

o BUG FIX: egsub() would return an invalid expression if the input had
  definitions of functions without arguments, e.g.
  egsub("x", "x", substitute(y <- function() 0)) which would throw
  "Error: badly formed function expression" if deparsed/printed.
  Added package test for this.
