Summary: unknown parsing error

Initial Comment:
I am getting "unknown parsing error" when trying to run 
a script with a following first line: 
#@+leo-encoding=cp1251.

If I add a couple of empty lines or 
# -*- coding: cp1251 -*-
then everything is ok.

I am using ActiveState python 2.3.3 on
Win2K server.

---------- Python ----------
error=22
  File "test.py", line 1
SyntaxError: unknown parsing error

Output completed (0 sec consumed) - Normal 
Termination
------------------------------
#@+leo-encoding=cp1251.
#@+node:0::@file test.py
#@+body
for i in range(5):
	print i
#@-body
#@-node:0::@file test.py
#@-leo

Martin, I hope you don't mind me assigning this to you.  I
think you implemented the coding spec.  I briefly read the
PEP and while the code does what the PEP states (ie, use a
regex), the behaviour doesn't match the examples.  It also
seems like it could be error prone to allow r'#.*coding[:=]'

I think there are two issues.  
1) in pythonrun.c in E_DECODE there is a missing break
2) the check for # -*- coding is not strict enough
    The patch makes the check r'# (-\*-)? coding[:=]'

The attached patch addresses both issues, although I'm not
sure you will agree #2 is a problem.  

Feel free to checkin, assign back to me or whatever.  I'm
not sure what the error message in pythonrun should be,
right now it's "unknown decode error."  Perhaps that should
be "invalid encoding" or something?
