reword misspelled spans to only the word. closes

Right now there is a bug with /** style doc comments, but /// doc comments work perfectly.


Just wanted to put this up to motivate me to try and do more later, because I am good for the night now :)

nope, the hi of the span is the lo + the length, if you added amt, youd go way out there.

unless my math is really crazy?
