[Pythonmac-SIG] Line endings and readline()

I do it this way:

	def	readline(self):
		s = self.chBuffer
		self.chBuffer = ''
		while 1:
			c = self.f.read(1)
			if not c: break
			if c == '\n' or c == '\r':
				if c == '\r':
					c = self.f.read(1)
					if c and c != '\n': self.chBuffer = c
				s = s + '\n'
				break
			s = s + c
		if s != '': self.cLines = self.cLines + 1
		return s

This is a method of an object (self) that serves as a general-purpose 
line reader. It has a field f, which contains the result of an open() 
call (or maybe a  urllib.urlopen() call).

This recognizes either '\r', '\n', or '\r\n' as a single line break. 
<insanity> Go crazy with them. Mix and match in the same file! I can 
deal with it all! Muhahahahahahahaha! </insanity note="must be time 
for a break">

PS If there is any interest in this object I will be happy to oblige.
