The trap and jobs builtins can be used to report information about
traps and jobs. This works when they're called from the current
shell but in a child shell the required information is usually
cleared. Special hacks allow:
- trap to work with command substitution;
- jobs to work with command substitution or in a pipeline.
Neither works with process substitution.
- Relax the test for the trap hack so it also supports pipelines.
- Pass the command to be evaluated to forkshell() in evalbackcmd()
so trap and jobs both work with process substitution.
