From: Drew Adams
Subject: bug#19975: 25.0.50; Add %s-like descriptor to `format' that treats nil like empty string
Date: Sun, 1 Mar 2015 07:32:56 -0800 (PST)

Enhancement request.  Add a new format descriptor to `format' that would
behave just like %s except that a nil argument would be treated as if it
were "".

This is a convenience only, to obviate needing to pass an argument such
as `(if something "foobar" "")' or needing to combine use of `format'
with use of `concat'.
