Feature request: almost correct cards

[iopq]

One of the harder things in Korean is to learn where the spaces go. Even Koreans sometimes write without spaces at all.

I fail some of my cards completely because I didn't put a space in a place where it must appear. Maybe for certain things like spaces and apostrophes it could just warn you that you're "almost there" to remind you to put the space in. It means you know the word, but forgot the exact rule for what is a word and what isn't.
