 Log Message:
 PR bin/54743
 
 If a builtin command or function is the final command intended to be
 executed, and is interrupted by a caught signal, the trap handler for
 that signal was not executed - the shell simply exited (an exit trap
 handler would still have been run - if there was one the handler
 for the signal may have been invoked during the execution of the
 exit trap handler, which, if it happened, is incorrect sequencing).
 
 Now, if we're exiting, and there are pending signals, run their handlers
 just before running the EXIT trap handler, if any.
 
 There are almost certainly plenty more issues with traps that need
 solving.   Later,
 
 XXX pullup -9
 
 (-8 is too different in this area, and this problem suitably obscure,
 that we won't bother)     (the -7 sh is simply obsolete).
