     I was planning to, eventually, write a script that filters out
     blank lines from both files passed as arguments and then passes
     the filtered data along to diff.  If we use any other nonportable
     options, then it may be possible to handle them the same way.

I think this is the best way.  Just replace 

 diff -B -b -w file.list - << EOF
EOF

with something like

 diff file.list - << EOF
EOF | sed -e 's/^[\t ]*$//'
     
Hopefully all seds should recognise this (I'm not too sure about the return 
status of this pipeline though.  Have to think about it a bit more....)
