more splitting travails

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

There's nothing harder than really getting on top of splitting issues :(

I have a file with blank lines in it, I read it into a variable then 
pass that variable to a function " % n_list $var ".  Inside the function 
I assign to a local variable 'List'.  The file/variable has five lines 
of data and four blank lines.


    #    local List=( "$@" ) # ONE element but $List prints correctly 
with spaces (nine lines).
    #    local List=( "${=@}" ) # FIVE elements but blank lines are 
gone (prints five lines).

How can I end up with nine elements and it prints correctly too? If it 
were a 'normal' variable I know this works:

    List=$some_variable[@]

... but:

    List=$@[@]

... doesn't work and looks sick and twisted anyway.

Other various attempts give me the number of elements being the 
character count.  Weirdly there's places where I iterate over all the 
lines in 'List' and it *counts* nine, but only displays five.

I could pound away at this but I'm going to just ask the people who 
understand these things.
