* src/term.c (encode_terminal_code): Each character from an
automatic composition is a multibyte character, so its multibyte
representation can take up to MAX_MULTIBYTE_LENGTH bytes.
Account for that when allocating storage for characters to be
encoded. (Bug#40913)
* test/lisp/simple-tests.el (with-shell-command-dont-erase-buffer):
Fix debug spec. Format command to run also under tcsh.
(simple-tests-shell-command-39067)
(simple-tests-shell-command-dont-erase-buffer): Quote newline in string.
Reported by Hugo Daschbach.
* lisp/calc/calc-ext.el (calc-init-extensions):
Remove calc-kbd-report key binding and autoload; it was removed in 2005.
calc-keypad-x-{left,right,middle}-click were renamed to
calc-keypad-{left,right,middle}-click in 2001; fix the autoloads.
calc-twos-complement-mode is a variable, not a function; remove the
autoload.
* lisp/calc/calc-prog.el: Remove commented-out calc-kbd-report.
* lisp/doc-view.el (doc-view-ghostscript-program): Use plain command
name instead of qualified name returned by executable-find (as
suggested by Stefan Monnier). (Bug#36357)
