Pipes only cause problems outside quotes, but I can see your point if 
someone commits without them (although I cant think of any module that 
doesn't use quotes for things like this ;P). The reason I did it like 
this is because it keeps the code shorter much simpler.

To make it work with that many arguments, you'd probably end up changing

   for TARGET ; do

to this:

   while [[ -n "$1" ]]; do
     $VALUE=$1
     $DESC=$2
     shift;shift

and adjusting the rest accordingly. Though, i'm not sure if you'd have 
scope issues with the $1 in the while statement.
