My bad! I had double quotes in my alias. When I changed it to single, it's all good. This is genuinely huge for me. Thank you again!

Can confirm that these steps work, @syneart , thank you again! I can launch app and, from the command line, diff both files and directories. Your patch seems to give me everything I really expect from Meld, so I'm crazy happy that I don't have to start using diffmerge or something else that just isn't as good.
