Improve menu structure for promptless choices

Promptless choices can appear "legitimately" if you define a named
choice in multiple locations to add on some symbols (which is broken in
the C tools though).

Prior to this fix, the promptless choice would get flattened, with the
choice symbols appearing in the same menu as the (invisible) choice.
This looks confusing.

Skip flattening promptless choices to fix it.
