Ah, *hm*, well, the code seems to implement \s instead of \w:

            // Match "Password: " with the regex ^[^:]+:[\w]*$.
            for (i=0,j=0,colon=0; i<line.length(); i++)
            {
                if (line[i] == ':')
                {
                    j = i; colon++;
                    continue;
                }
                if (!isspace(line[i]))
                    j++;
            }
            if ((colon == 1) && (line[j] == ':'))
            {
               ...

So I still fail to see how the code would match
	"su: you are not allowed to su root"

Cheers,
Waldo
