Alex,

You're _literally_ right :-). But that doesn't mean that it 'reads right'; my 
intention was to say,

  'I want my lines joined using commas as delimiters',

not:

  'Comma, please join these lines for me.'

btw, this particular discussion is already a few years old, and there's 
nothing that can be done about it (and I found myself using it lately, so it 
may be the right way to say it after all...)
