Too many "not"s in one sentence, and too many nested "echo"s in
the other.

But when I try to run

    #!/bin/bash
    echo $(echo 42  # print 42)
    )
    echo there

it returns

    42
    there

as expected.  IOW, I agree with the title of this bug report (and in my
test, Emacs doesn't highlighted any part of that script with the comment face).
