As a person relatively new to emacs, I can remember that those various
uses of TAB made my first steps a bit more difficult. Now in my
config, TAB is rebound for almost every mode I use, see below.

I'm really surprised to see how many people here have done their own
implementation of this behaviour. FWIW, here is mine, fairly naive,
but functional.

(defun indent-for-tab-or-expand (expand-fct)
  "Indent line if not yet, otherwise call parameter function."
  (interactive)
  (let ((ppos (point)))
    (indent-for-tab-command)
    (if (and (looking-at "$") (not (looking-back "^\\s-*")) (eq ppos (point)))
	(call-interactively expand-fct))))

(defun indent-for-tab-or-dabbrev-expand ()
  "Indent line if not yet, otherwise call dabbrev-expand."
  (interactive)
  (indent-for-tab-or-expand 'dabbrev-expand))

(defun indent-for-tab-or-hippie-expand ()
  "Indent line if not yet, otherwise call hippie-expand."
  (interactive)
  (indent-for-tab-or-expand 'hippie-expand))
