Works just fine with GNAT GPL 2015.

Try to print Length (Buffer) as well to see how long the string actually
is. You could have problems with controlling characters.

1. When dealing with character files, it is better to use Stream I/O
instead of Text_IO and recognize line ends manually instead of Get_Line.
The way the protocol defines line termination might be incompatible with
one of Get_Line and/or the OS.

2. Buffer should be an "in out" parameter. It is not a big difference in
this case, but cleaner.

3. You should never use End_Of_File. It might be quite expensive or not
working, e.g. some the protocol may deploy explicit terminators, like EOF.
Exit file read loops with End_Error exception.
