tap/awk: improve comments about Korn shell signal handling issues * lib/tap-driver.sh: Link an Austin Group discussion about how shells are allowed, and even encouraged, to set the special variable `$?' to values greater than 256 to report termination of a child by a signal. Improve and extend comments about our workarounds for unusual korn shell signals' propagation. Thanks to Eric Blake for the pointers.
