'Push a line of source text to the interpreter
The line should not have a trailing newline; it may have internal
newlines. The line is appended to a buffer and the interpreterâs
runsource() method is called with the concatenated contents of the
buffer as source. If this indicates that the command was executed
or invalid, the buffer is reset; otherwise, the command is incomplete,
and the buffer is left as it was after the line was appended.
The return value is True if more input is required, False if the line
was dealt with in some way (this is the same as runsource()).'
