BUG/MINOR: sample: Make the `word` converter compatible with `-m found`

Previously an expression like:

    path,word(2,/) -m found

always returned `true`.

Bug exists since the `word` converter exists. That is:
c9a0f6d0232cf44d6b08d1964b9097a45a6c65f0

The same bug was previously fixed for the `field` converter in commit
4381d26edc03faa46401eb0fe82fd7be84be14fd.

The fix should be backported to 1.6+.
