[issue32880] IDLE: Fix and update and cleanup pyparse

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

Is
        str = str.replace('xxxxxxxx', 'x')
        str = str.replace('xxxx', 'x')
        str = str.replace('xx', 'x')
        str = str.replace('xx', 'x')
really faster than
        _squashex = re.compile('x+').sub  # top of file
        _squashex('x', str)

And are the name bindings faster that regex.func(...)?
