bug#1469: patch for term.el regression when dealing with long lines under bash

(I sent this to the wrong list earlier.  Resending to, hopefully, the 
right place this time.)

Here's a patch for bug#1469 (term.el regression when dealing with long 
lines under bash).

* term.el (term-emulate-terminal): Decode substring just prior to 
inserting it.  (Bug#1469)

bug#1469 was introduced while fixing bug#1006.  I verified this patch 
against the repro steps in bug#1006 to make sure I haven't made a 
regression.

Can someone please review?  I'd appreciate any feedback.
