Summary: Malformed data at end of patch is  treated as sender

Initial Comment:
When opening a patch file Pd doesn't check correctly if
all messages are well-formed. Inserting a line at end
of a patch file, that starts with a symbol and ends
with a ";" will treat the leading symbol as a
receive-target and will send the rest of the line to
that receiver. 

For example inserting: 

pd dsp 1;

at the end of a patch will switch on audio, even when
the patch is started with "pd -noloadbang". 

While this message is harmless, other messages may do
nasty things and open a security hole. 

Attached is a patch that illustrates this behaviour,
also see this pd-list message thread:
