Re: [PATCH 2/2] branch, for-each-ref: add option to omit empty lines

It however theoretically can break an existing use case where the
user correlates the output with a list of refs they externally
prepared (e.g. "for-each-ref --format... a b c" shows "A", "", and
"C", and the user knows "b" produced "").  I do not know how likely
such users complain, though, and if there is nobody who relies on
the current behaviour, surely "unconditionally omit" is a very
tempting approach to take.

Thanks.

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.

That makes two of us ;-)

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.

Yeah, but this v2 is not starting with purely a new feature without
breaking anybody, so we can stop here for now, and once there is
enough interest to go through the deprecation dance, we can do that
as a separate series later.

Thanks.
