When list_and_choose() function is letting you choose more than one
items, its prompt becomes ">> ", instead of "> " that is used for a
singleton choice. To that prompt, you can say "3-7" (Add these 5
items
to the choice), "*" (I want all of them), "-2-4" (exclude 2 and 3
and 4
from the set I have chosen so far). These are also "hidden", and need
to be documented, but that would be a separate patch.
I was just about to prepare some documentation for this when I saw
that it is already documented, and by none other than you, Junio! (see
6a5ad23d).
Unless by "documentation" you meant to somehow expose these in the
interface at runtime... something like this? (applied on top of the
patch I just sent to the list):
