Yeah, in this case, I meant in principle.

What I have is two functions, one that
searches, and one that "searches again" with
the previous search string as input.

When the function that searches is invoked, it
asks for a search string, but if it isn't
provided, the default (i.e., previous) string
is used even tho the better way to do that is
to invoke the function that searches
again directly.

I can extract into a function the code that
fetches the previous search *but* how do I use
that in the interactive form as well as outside
it without computing twice? As was instructed
here - (info "(elisp) Programming Tips") - only
even in the provided example, it really didn't
happen that way at all.
