This commit adds backward-word, backward-kill-word, forward-word, forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B, Alt+D and Alt+Backspace respectively. It is disabled by default and can be enabled via MICROPY_REPL_EMACS_WORDS_MOVE. Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W. The features are enabled on unix micropython-coverage and micropython-dev.
This directory doesn't contain real tests, but code snippets to detect various interpreter features, which can't be/inconvenient to detecte by other means. Scripts here are executed by run-tests at the beginning of testsuite to decide what other test groups to run/exclude.
