When the macro %{some text} is used in a user menu entry, and nothing is typed — if only key <enter> is pressed —, the rest of the commands are not run, as if the script exited.

I'm not sure if this is the expected behavior. The man page doesn't mention anything, only that F10 or ESC can cancel.

It would be interesting if the script didn't exit, so that the variable receiving the text from the macro could be tested for empty/undefined.

Steps to reproduce

1. Create a user menu entry like this one:

x   testing
    text=%{enter any text}
    echo "text = $text"

2. Run the user menu, select this entry, and press <enter>

3. Press ctrl-o to check if there was any output

There will be no output, as if the script exited before echo "text = $text was run.
