- * FIXME : merge with countChars. The structures of the two functions
- * are similar but, unfortunately, they seem to have a different
- * notion of what to count. Since nobody ever complained about that,
- * this proves (again) that any number beats no number ! (JMarc)
- * We have two use cases:
- * 1. Count the words of the given range for document statistics
- * - ignore inset content without output. (skipNoOutput == true)
- * 2. Count the words to present a progress bar for the spell checker
- * - has to count whole content. (skipNoOutput == false)
