OK. Here's how fc has worked historically: it internally turns on the
-v option after running the editor and evaluates the contents of the
resultant file. This is so you can see what happens to the edited
commands. (It's an open question whether or not this should be -x
instead, but it never has been.) The -v option doesn't discriminate
between commands read from the input stream and commands executed by a
trap. I assert that it's not counterintuitive -- it's the same thing
that happens when you run the same commands from a prompt.
