Default tab-complete does not work

[manuel-uberti]

Expected behavior

TAB-complete works as described in the docs.

Actual behavior

Nothing happens when I press TAB.

Steps to reproduce the problem

• emacs -Q
• M-x package-initialize
• visit a Clojure file (e.g., I used my utils.clj)
• Jack-in with C-c C-x j j (I had to press RET on clojure-cli for that specific file)
• C-c C-k
• Try to tab-complete (e.g., in that file at line 17 I typed (jf/ and pressed TAB)

FTR, I bumped into this when testing Corfu, see minad/corfu#8

Without special configuration it's M-TAB, not TAB (but this doesn't work in many window managers). If this doesn't work - I assume something related to completion got changed in Emacs 28.

[manuel-uberti]

M-TAB switch windows here on GNOME, you're right.

[manuel-uberti]

With (setq tab-always-indent 'complete) everything works. Sorry for the noise.

[bbatsov]

No worries. I've updated the docs with more details in case someone else gets confused by this.
