Currently, words in double quoted strings are spellchecked, but not strings with simple quotes.

My suggestion is to add a feature that would let codespell determine what a string delimiter is on a line by line basis, possibly limited to certain file patterns (extensions).

The detection would be on a line by line basis.

I understand that this could be somewhat tricky.

One way to implement it would be to have a regex that finds strings and replaces the delimiters of the string with spaces before looking for words.
