Daniel Hokka Zakrisson 6477bdc6fc Use a regexp to filter out arguments instead
pipes.quote is a bit overzealous for what we want to do, quoting ;
and other characters that you most likely want to use in your shell
invocations. The regexp is the best I could come up with to be able
to only replace the parts of the arguments that shouldn't be
executed.
