Description of Problem:
"aspell -c FILE" / "ispell FILE" claims that "proven" is not a word.
http://www.m-w.com/ claims it is a word.
Easily reproducable with a file that contains "proven".
rpm -qa|grep aspell
aspell --add-extra-dicts english-variant-1 -c foo
(with foo containing proven, or a misspelled version thereof) works for me.
I don't know why it's in the variant part.
