[gradsusr] passing whitespace from bash to grasds run

[Simon Kiertscher]

Hi John,

thx for your idea with the IFS. But i think this does not because i pass 
the arguments to a GrADS Skript and i think GrADS will separate the 
arguments, thus i had to manipulat the IFS of GrADS or not?
However, export IFS=$'\n' before my grads call does not work.

I also tried already escaping ticks like \"$two_arguments\" or 
\'$two_arguments\'.
If i do it like that, i get (if  two_arguments=foo bar) "foo as the 
first argument and bar" as the second one.

Any other idea what i could do?
Thx again and Best Regards,
Simon
