Subject: IDLE bug?

Please forgive me if this is not the proper place to send bug reports. 
There was no link clearly available on the IDLE page at python.org, and 
this address is listed there.

I have a python script that, towards the beginning of the file, contains 
a 245-line triple-quote string, as a template for a data file.  When I 
open the script in IDLE, it stops syntax-highliting at the 116th line of 
the string, and prints an error message in the IDLE shell:

===
Exception in Tkinter callback
Traceback (most recent call last):
   File "/usr/lib/python2.2/lib-tk/Tkinter.py", line 1300, in __call__
     return apply(self.func, args)
   File "/usr/lib/python2.2/lib-tk/Tkinter.py", line 436, in callit
     apply(func, args)
   File "/usr/lib/python2.2/site-packages/idle/ColorDelegator.py", line 
144, in recolorize
     self.recolorize_main()
   File "/usr/lib/python2.2/site-packages/idle/ColorDelegator.py", line 
207, in recolorize_main
     m1 = self.asprog.match(chars, b)
RuntimeError: maximum recursion limit exceeded
===

If I position the cursor at the end of the 116th line and hit enter, it 
will then syntax-highlite the rest of the script, and appears to 
continue without further errors.
