I ran etags like this:

etags ./eval.c -o $(pwd)//.retags.d/Q

Note the double "/".

The resulting tags file contains this line:

../../eval.c,567

But this is wrong, there should be only a single "..".

I think relative_filename needs to handle the situation where multiple
"/"s appear consecutively.  The appended patch worked for me.
