Sean Bright bf7c808604 func_env: Prevent FILE() from reading garbage at end-of-file ...

If the last line of a file does not have a terminating EOL sequence, we
potentially add garbage to the value returned from the FILE() function.

There is no overflow potential here as we are reading from a buffer of a
known size, we are just reading too much of it.
