bug#34474: Save last search string between sessions

[積丹尼 Dan Jacobson]

You know just the other day I was reading
(info "(emacs) Repeat Isearch")
and thinking, oh the mighty emacs, doesn't even have an option to save
the last search string between session, like the puny less(1) can.
Let's see, you could save it in .emacs.d/* somewhere.
(Yes, I'm sure somebody has already implemented this as an add-on.)
(Sure, you might say well then also save the last yank area too, etc.
but I didn't say that.)

Ah yes, say goodbye to every morning:
"I-search:  [No previous search string]"
(which by the way doesn't show up in *Messages*)
