Between versions 5 and 8 the output of "show env" changed. Currently  
we use version 7 code and my changes are below, your milage may vary  
depending on how your ERX is configured (ie dual SRPs/fileSync/HA  
etc), we now run a HA setup, pre 7 we used fileSync.

I fixed it for us by editing the "sub ShowEnv" subroutine in the  
jerancid script to look like this.

Also under DirSlotN I found the need to add a extra regex to avoid  
false diffs.

These changes have avoided 99% of the false diffs for me.
