Fix problem with non-ASCII characters in ediff error messages
* lisp/vc/ediff-diff.el (ediff-prepare-error-list): Decode the
data from diff before displaying (bug#5050). This fixes a problem
with displaying raw bytes in the error messages in non-ASCII locales.
Make image-mode give better feedback when the buffer is empty
* lisp/image-mode.el (image-mode): Give a less confusing message
if we don't have any image data (bug#16062). Also leave the
buffer in fundamental mode.
Fix NS crash on invalid frame title string (bug#42904)
Instead of blindly assuming that all Emacs strings are valid UTF-8,
which they are not, use a more careful conversion going via UTF-16
which is what NSString uses internally. Unpaired surrogates will
still go through to the NSString objects, but the NS libs handle them
gracefully.
* src/nsterm.h (EmacsString): New category.
* src/nsfns.m (all_nonzero_ascii): New helper function.
([NSString stringWithLispString:]): New method.
(ns_set_name_internal): Use new conversion method.
Don't message the hunk status when just going to it
* lisp/vc/diff-mode.el (diff-goto-source): Don't output a status
about the hunk just when jumping to it (bug#38370). This would
output "Hunk already applied" when browsing diffs.

Allow searching interactively over completions in `M-x'
* lisp/simple.el (read-extended-command): Allow doing interactive
searches over the completions (bug#12490). This restores the

* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-check-1)
(test-byte-opt-arithmetic, bytecomp-lexbind-check-1)
(bytecomp-lexbind-explain-1):
When comparing interpreted with compiled results, don't consider all

arguments may differ, but there may be good reasons for that.)
* test/lisp/emacs-lisp/bytecomp-tests.el
(test-byte-comp-macro-expand-lexical-override): Remove functions
before testing so that the test can be run twice without failing.
Signal an end-of-file error upon errors when reading from stdin
* src/minibuf.c (read_minibuf_noninteractive): Signal an
`end-of-file' error when reading from stdin instead of a general
error (bug#34123). This makes it easier to write code that
recovers from this situation.
