My understanding of the discussion is that some versions of zsh require 
"-e", at least in some circumstances.  I've applied a patch to use "-e" 
with zsh.

The original reporter was too emotional to mention his version of zsh.  
And by the way, I did test the original code with bash, tcsh and zsh, so 
the subject "Sick way of chdir'ing incompatible with non bash shells" is 
misleading.

For that matter, using printf (as Clint Adams suggested) would be better,
since reading the filesystem is faster that writing to it.  But I don't 
think we are forced the abandon "echo".
