I've now updated any prompt I could find to use `format-prompt' (by
grepping for " (default ").  Maybe I've missed one or two, but that
should mean that that the overwhelming majority of our prompts now
respect `minibuffer-default-prompt-format'.  See commit 6640942221.

With that, I think the option `minibuffer-eldef-shorten-default' should
be declared obsolete, as in the attached patch, and consequently removed
from the manual.  This change should go to master, of course.

The command `minibuffer-electric-default-mode' shouldn't be declared
obsolete as it does something different.
