I actually instinctively expected for-each-ref to suppress empty lines, at least by default. I don't see a good reason for them, except for something along the lines of what you said. We can of course make it a config option along with the flag, then after some time flip the default, and perhaps ultimately remove the config option again. Perhaps in a v3 if there is enough interest; will send a v2 shortly. But I must admit I am not very motivated to follow that up down the line. Øsse
