* should echoing be on and ignErr becomes another printf template for
* executing the command while ignoring the return status. Finally errOut
* is a printf template for running the command and causing the shell to
* exit on error. If any of these strings are empty when hasErrCtl is FALSE,

Posix says we should execute the command as if run by system(3)
Expect 'Hello,' and 'World!'
Hello,
World!
a command
a command prefixed by '+' executes even with -n
another command
make -n
echo a command
echo "a command prefixed by '+' executes even with -n"
a command prefixed by '+' executes even with -n
echo another command
make -n -j1
{ echo a command

echo "a command prefixed by '+' executes even with -n"
a command prefixed by '+' executes even with -n
