sybase style stripslashes

if add/stripslashes are operating in sybase mode (magic_quotes_sybase is on), there appears to be a little weirdness. addslashes will replace single quotes with double single quotes and will backslash escape null characters. stripslashes will replace the double single quotes with single quotes, but will not unescape the null characters. is there a reason for stripslashes not to unescape null characters, or should it be changed to do so? (it's an obvious change, but I didn't want to make it without asking.) --jlp
