more about GIOChannel

[Ron Steinke <rsteinke w-link net>]

Owen,
	A few more things about the GIOChannel implementation:

1.	There is a case where when only need to open one converter
	on an encoded channel: when the file is read only or write only.
	I've modified the code to reflect this.

2.	One capability the current API doesn't have is the ability
	to read one character at a time, due to the variable width
	of UTF-8 characters. It would be fairly easy, with the
	current back end, to add a function to do this. Is it
	too late in the API freeze to do this, considering that
	the whole GIOChannel interface is essentially one huge open
	API bug?
