It's mostly just an optimization thing, so not hugely important (at the
time, Ken was working on a pure Lisp dumping strategy, so shrinking the
preloaded code was important for that, but we've gone with the pdumper
instead).  However, I seem to recall that applying something like this
will make it possible to solve Bug#4845, because the docstring loading
mechanism will no longer be reliant on finding "(defun foo" in the .elc
file.  So that might be nifty.
