+Subject: kern/misc: Make grub_vsnprintf() C99/POSIX conformant
+
+To comply with C99 and POSIX standards, snprintf() should return the
+number of bytes that would be written to the string (excluding the
+terminating NUL byte) if the buffer size was big enough. Before this
+change, the return value was the minimum of the standard return and the
+length of the buffer. Rarely is the return value of grub_snprintf() or
+grub_vsnprintf() used with current code, and the few places where it is
+used do not need to be changed.
