X Title: gh-146044: Fix ctrl-w (unix-word-rubout) to use whitespace word boundaries by kimimgo · Pull Request #146174 · python/cpython

Description: Fixes #146044 Summary The unix-word-rubout command (ctrl-w) was using bow() which treats punctuation as word separators via the syntax table. This differs from bash/readline's unix-word-rubout which uses only whitespace as boundaries. Changes reader.py: Add bow_whitespace() method — same as bow() but only considers spaces and newlines as word boundaries commands.py: unix_word_rubout now calls bow_whitespace() instead of bow() test_reader.py: Add TestBowWhitespace class with 4 tests verifying the whitespace-only behavior and the difference from bow() Example With buffer foo.bar baz and cursor at end: Before: ctrl-w deletes baz, then bar, then foo (3 operations) After: ctrl-w deletes baz, then foo.bar (2 operations, matching bash) The existing bow() method used by backward-kill-word (M-Backspace) is unchanged.
