[PATCH] src/sort.c: assert on saved.text before calling memcpy()

[Kovarththanan Rajaratnam]

clang detected the following false positive:

sort.c:2435:15: warning: Null pointer passed as an argument to a 'nonnull' 
parameter
              memcpy (saved.text, smallest->text, saved.length);
              ^       ~~~~~~~~~~

When we reach this line saved.text is guaranteed to be non null.
