bug#15616: 24.3; Setting lexical-binding in file's local variables block should trigger a warning

[Ryan]

Actually, my testing indicates that the documentation is inaccurate: 
lexical-binding can be set via either the first line or a local 
variables block, and it will take effect in both cases when the file is 
compiled. This is on version 24.3.1. So I guess the documentation just 
needs to be updated.
