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

clang detected the following false positive:

sort.c:2292:7: warning: Null pointer passed as an argument to a 'nonnull' parameter
      memcpy (temp.text, line->text, line->length);

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