So far so good, but I'm comparing the second Tab in scenario #2 to the
first Tab in scenario #1 because they are both in states characterized
by:
a. a valid response
b. a non-unique completion
c. no information yet communicated to the user about b
Of course one is in ~/ while the other is in ~/Desktop/, so to make
my point clearer I've construed the alternative scenario:
Scenario #3:
. User types M-x cd RET ~/Desktop RET (or launches emacs from ~/Desktop)
. User presses C-x C-f TAB
. Emacs says [Complete but not unique]
. User presses TAB once more
. Emacs pops up *Completions* and still says [Complete but not unique]
The way the user reached ~/Desktop in scenarios #2 and #3 is
irrelevant to me, the fact that s/he has typed Tab before or not is
not adding anything to the fact that the ongoing completion is now
~/Desktop/ and the user still doesn't know whether it's unique or not.
That's why I cannot make sense of the difference in behavior.
