My fix to the locations for NUL-terminators in substring_loc changed
the output for gcc.dg/tree-ssa/builtin-sprintf-warn-4.c, leading to a
couple of FAILs from that test. Sorry; my testing of the earlier patch
was incomplete (I needed to rebase).
I've committed the attached patch to trunk (r240442), which fixes the
test failures.
