Modified Files:
        src/bin/sh: eval.c

Log Message:
PR bin/54743

Having traps set should not enforce a fork for the next command,
whatever that command happens to be, only for commands which would
normally fork if they weren't the last command expected to be
executed (ie: builtins and functions shouldn't be exexuted in a
sub-shell merely because a trap is set).

As it was (for example)
        trap 'whatever' SIGANY; wait $anypid
was guaranteed to fail the wait, as the subshell it was executed
in could not have any children.
