Package: bash Version: 4.4-1 Severity: minor Dear Maintainer,
bash 4.4-1 contains an allegedly regression wrt handling of ^W (Control-w) in vi-mode. After having red https://lists.gnu.org/archive/html/bug-bash/2016-09/msg00018.html, the obvious suspect seems to be > 2. New Features in Readline ... > m. The default binding for ^W in vi mode now uses word boundaries > specified by Posix (vi-unix-word-rubout is bindable command name). I could not find any documentation about 'vi-unix-word-rubout'. Anyway I'm not tagging this issue as 'upstream' as I haven't checked. $ set -o vi $ echo REMOVE maintain With bash-4.3-15 I can recall and modify the line positioning the cursor on the space between 'REMOVE' and 'maintain' and using ^W: Esc, k, e, e, l, i, Ctrl-w With bash-4.4-1 this doesn't work (does nothing), and I have to position the cursor on the start of the next word: Esc, k, w, w, i, Ctrl-w, Ctrl-w Anyway, it DOES work if I try to remove only part of the word (e.g.: leaving the last E): Esc, k, e, e, i, Ctrl-w Where it really becomes nasty is in presence of non alphanum chars: $ echo REMOVE .maintain Positioning the cursor on the dot succeeds in removing the space but then stop working: Esc, k, w, w, i, Ctrl-w, Ctrl-w OTOH, positioning the cursor on the char following the dot works (but in this case removes space and dot together as if there are no word boundaries): Esc, k, w, w, w, i, Ctrl-w, Ctrl-w Trying to modify a line like $ ls /tmp/ /var/ with ^W can be frustrating depending on where you start from. As from my limited tests, this issue does not seem affected by locale settings.
