In your case you are intending those double quotes to directly become characters in the output (as opposed to them being used internally as delimiters for macro arguments). In this situation it may be helpful for possible future readers of your groff code to actually insert them as "special" characters in your code, i.e., instead of .CW "$ echo ""foo bar""" write .CW "$ echo \[dq]foo bar\[dq]" and use " exclusively as a macro argument delimiter. (Then there should also be no problems if you later decide to rewrite the .CW macro and make it pass its argument to still another macro.) (You are going to have to go through all of the example command lines anyway and convert the quotes, so I don't think this is going to be more work.)
