Hi folks,
What follows is a diff that presents Doug's changes (which must have
required quite a bit of effort, thanks!) in a slightly different format
which I think the grumpies here might prefer.
Specifically, case statements look more like what a lot of folks are
used to seeing, and conditionals that don't need to be case sensitive
have not been converted to case statements.
I think the effort which Doug has put into this is great and would make
for a better rc. It's a pity that a few cosmetic issues generated so
much pooh-pooh'ing. :-(
Ciao,
Sheldon.
