Bug 331509

I am very grateful for the separate options to ignore capitalization (which I use) and diacritics (which I don't use) in the written practice mode. I suggest to add a third (and possibly fourth) option to ignore punctuation and whitespace. (My file contains many full sentences with proper punctuation which I want to keep in the file and see when the correct answer is shown - but which I do not need to practice entering! And if a hyphen is ignored, then so should be at least one of the spaces around it, which would be best achieved by ignoring all whitespace changes. Indeed, it sometimes happens to me that I accidentally enter two spaces instead of one. Not only does this lead to the item marked as answered wrongly, but I always spend quite a while trying to decypher what was wrong with my answer.)

Reproducible: Always
