You are much more familiar with the code, but I suspect that a simple 
change would fix that:

Just use "--offset >= 0 && cwd[--offset] != '/'" here.  And maybe 
ceil_offset = -1 again.

I cannot quickly test, since I am short on time, and it would be too 
cumbersome to find which patches to apply first.

But I strongly believe that it is not beyond your capabilities to adjust 
Hannes' patch for your command series, keeping the elegance.
