The problem is that the special characters have to be re-escaped if
the parameter is sent to some other program. Imagine a simple (somehow
foolish) script:

echo "Number of parameters = $#"
if [ $# -eq 1 ]
  ./param $1

If you call it with an escaped space within the first parameter, you'll get:

[wagner at cluster1 wagner]$ ./param some\ text
Number of parameters = 1
Number of parameters = 2

Beware! If you call this script with one parameter, you will fall into
an endless loop!
