I have a file en.utf-8.add in the folder of a file being edited by Vim. I issue :mkspell! en.utf-8.add to create a new en.utf-8.add.spl. In the edited document, the word int is not flagged as a spelling error. I also have a ~/.vim/spell/en.utf-8.add and a corresponding en.utf-8.add.spl with the same date/time, but the en.utf-8.add also does not contain the word int.
Why is int considered correct? What else can I examine to track down the reason?
I have fileencoding=utf-8 and spellfile=en.utf-8.add. I confirmed that the latter takes effect by removing some words and seeing them flagged after the mkspell! en.utf-8.add command. Of course, I add the words back.
