Subject: lib/string/README: streq(3) and strnul(3) are in libc
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=430bfc20aa3029c4529b85b214e41890c0148053;p=thirdparty%2Fshadow.git

lib/string/README: streq(3) and strnul(3) are in libc

streq(3) and strnul(3) are now part of a libc implementation: gnulib.
They are also documented in a manual page.  Thus, refer to them as
streq(3) and strnul(3).
