I applaud this.  I've often considered doing the same but avoided it
because it was easier than fighting the bikeshed :)

I don't use the first two aliases, so I don't care about them at all.  I
do however disagree strongly with changing the default options on such a
widely used command.

This change is disruptive, and it can affect use of ls(1) in scripts.
For example, it even sticks the extra characters in the output of
"ls -1" (the number 1), which is specifically designed to be used when
piping the output elsewhere.  Please do not break this.  It is also
distracting - If I want to see what type of file a particular entry is,
why not just run "ls -l"?

It's like the tendency some Linux distributions have of 
"alias mv mv -i", although that can at least be overridden on the
command line with "-f".  The "ls -F" change cannot be overridden without
unaliasing.

I can't comment as I didn't say my suggestion should be default - but
for me the above isn't a bad choice.  I would however prefer:
set prompt = "%n@%m:%c04 %# "
and not
set prompt = "[%n@%m]%c04%# "

as that then gives you user@host:path in exactly the same format as you
need to use with scp, etc.

It's been in there forever.  I think this should stay, it would just be
too disruptive otherwise.
