Handle completely undecoded input in term (Bug#29918)
* lisp/term.el (term-emulate-terminal): Avoid errors if the whole
decoded string is eight-bit characters. Don't attempt to save the
string for next iteration in that case.
* test/lisp/term-tests.el (term-decode-partial)
(term-undecodable-input): New tests.
