Remove strsep() call
strsep() is not a POSIX function, and it means that every system needs different defines to expose it. If the prototype of strsep is not exposed then an ugly int/pointer is done and it might mean a crash. The best solution?, to remove the strsep and make a custom loop. If C programmers cannot do this kind of loops without calling a library function, then maybe we should move all the suckless software to Java.
