More than one cursor position match found

Error message

More than one cursor position match found

What it means

cursor_position searches the cursor buffer's text for occurrences of the expected cursor excerpt and requires exactly one match; more than one match makes the cursor position ambiguous, so example loading aborts rather than guessing.

Solutions

1. Enlarge the cursor excerpt in the example spec so it is unique in the buffer
2. Regenerate the example with a longer, unambiguous excerpt
