+The following tab indented lines will cause a true vi with modelines
+activated to infinitely loop putting "Hello World" in the buffer. Hit
+ to abort the loop and see the output. None of the vi clones
+support modelines this powerful, and modelines are disabled by default.
+Set the environment variable EXINIT to "set ml" to activate modelines.

+Whitespace is largely insignificant, but these must be the last five
+lines in the file to work properly. Unless it is in "vi: ... :" or
+"ex: ... :" format, any preceeding text will be ignored.
