[PD] Error: invalid command name "pd"

[Jonathan Wilkes]

Oh, and if you do try this, make sure you only change the
"pd" tcl commands and not pd message selectors:

pd [concat pd init blah blah blah

Above, the first "pd" is a tcl command and should be changed to 
"pdsend".  However, the second "pd" is part of a string that gets 
interpreted by the core as the selector of a message (i.e., the receive 
symbol "pd").  The second part should be left as is.

But if you happen to accidentally change a selector you'll probably get 
an error to the Pd console, "pdsend: no such object".
