bug#14804: Gnus spelling fix: unexist -> nonexistent

[Paul Eggert]

Tags: patch

Recently Gnus added the 'unexist' flag with some
code that deals with 'unexistent' articles.  If I
understand the concept correctly, the usual
spelling in English is 'nonexistent'.  Here's a
proposed patch to use that spelling.
