This is a little annoying to fix, doing it properly requires embedding a markdown parser (or reusing the one in rustdoc). A hack workaround is to have a dictionary file with these common words (fsvo common), e.g. https://github.com/huonw/spellck/blob/01ccbbbbd35bdfde1e8f01314cf68b08099c95de/src/stdlib.txt

(It would be neat to spellcheck any comments inside the code blocks.)
