Hi all,

Since I didn't receive any replies to this, I'm forced to assume that
what I want to do isn't possible with GALib 2.4.5.  So, I decided to
patch my copy of GAParameterList.C with code to understand quotes and
backslashes, which results in a nice way to specify parameters with
embedded spaces.  [This was only necessary for
GAParameterList::read()... GAParameterList::parse() can already handle
spaces because of the way the command shell passes parameters to the
program.  As such, I left GAParameterList::parse() unchanged.]  If
anyone (especially Matthew) is interested in this code, let me know.
