Tags: patch This feature is the opposite of the feature implemented by Augusto in bug#61814. The problem is that the default behavior of flyspell-mode is too erratic. It checks and highlights random words where the cursor happens to travel while navigating the buffer. The feature from Augusto allows to check all words in the buffer that makes sense when the intention of the user is to see all misspelled words to correct them. OTOH, often there is no need to check all misspellings in the existing file, but only newly entered text. For such use cases extra highlighting while moving thru the file causes too much distraction. So here is a new option that allow to check only text edited by the user.
