+Patch 7.4.088
+Problem: When spell checking is enabled Asian characters are always marked
+ as error.
+Solution: When 'spelllang' contains "cjk" do not mark Asian characters as
+ error. (Ken Takata)

+THEOREM: VI is perfect.
+PROOF: VI in roman numerals is 6. The natural numbers < 6 which divide 6 are
+1, 2, and 3. 1+2+3 = 6. So 6 is a perfect number. Therefore, VI is perfect.
