Che vita intensa!\" (Tonino Carotone)\n\nThis patch fixes handling of embedded NULs using an approach similar\nto the one taken by NetBSD.  In particular, we first determine the\nlength of the output string, and then use a sequence of Xs of the\nsame length as input to the underlying C printf to determine the\namount of leading and trailing padding.  Finally we replace the\nXs with the actual string before writing it out.\n\nIn order to print out the temporary string containing Xs and padding,\na new helper xasprintf is added.  Unlike asprintf though, our\nxasprintf prints to the ash stack rather than using straight malloc\nmemory.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\n",
