This PR adds very basic normalization for extract strings to shrink consecutive whitespace characters to a single space, e.g.
"a b \t\t c"
->"a b c"

then issue 494 can be closed. Future requirements would go onto a different issue. I am waiting for a definition of what is considered "punctuation" before implementing this one.
