Note: original question posted on the RT users list. This is a follow-up
and possible solution.

Thanks to der Mouse for the shell tutorial. :)

I tried his suggestion and while I finally came to terms with my shell,
it confused the rt CLI. I was getting this with newlines:

rt: edit: No variables to set.

I messed around a bit and found that sticking the 'xms' at the end of
the regex seemed to make it work the way I wanted:

         elsif (/^set$/i) {
             my $vars = 0;

--->        while (@ARGV && $ARGV[0] =~ /^($field)([+-]?=)(.*)$/xms) {
                 my ($key, $op, $val) = ($1, $2, $3);

What I don't know is if this causes other un-wanted side effects with 
multi-line commands, thus my post to the dev list. Would this be a 
desired or worthwhile patch?
