I may be completely out in left field, so feel free to correct me if my
comments are off the mark...
I am worried that Sven's proposal may case some problems. I am
uncomfortable with using a syntax that depends on what many languages and
operating environments would consider to be unbalanced single quotes. I am
worried that these could end up causing great difficulties for example, when
starting the gimp with a script-fu script and related parameters from the
command line, on either *nix, or especially under Windows. Does anyone else
agree this could be a serious problem, or can someone essentially guarantee
that it isn't?
