Fix msg for verbose suggestions with confusable capitalization

Browse Source 
When encountering a verbose/multipart suggestion that has changes
that are only caused by different capitalization of ASCII letters that have
little differenciation, expand the message to highlight that fact (like we
already do for inline suggestions).

The logic to do this was already present, but implemented incorrectly.
