+# Suppress a valgrind message about use of uninitialized memory in memchr().
+# POSIX states that when the character is found, memchr must not read extra
+# bytes in an overestimated length (for example, where memchr is used to
+# implement strnlen).  However, we use a safe word read to provide a speedup.
