Merge Py Idle changes
Rev 1.4
SF bug 546078: IDLE calltips cause application error.
Assorted crashes on Windows and Linux when trying to display a very
long calltip, most likely a Tk bug. Wormed around by clamping the
calltip display to a maximum of 79 characters (why 79? why not ...).
Bugfix candidate, for all Python releases.
