`diff' package: Fixed off-by-one in string diff.
* src/guile/skribilo/package/diff.scm (add-unchanged): When `(null? edits)', check whether `(< str-pos str-len)' (was `(< str-pos (- str-len 1))'). This fixes off-by-one when diffing strings (last character didn't appear). git-archimport-id: lcourtes@laas.fr--2006-libre/skribilo--devo--1.2--patch-36
