No, it does not make sense to change the default. Emacs is just one of
many tools processing diff output. I remember gratuitous breakage of
git, too. There are far too many tools relying on the _documented_ diff
output formats (please read
(info "(diff) Context")
for a detailed explanation of the diff formats) that it makes sense
breaking things all around for no tangible benefit.
I don't understand why this change was made in the first place, and I
don't understand why people would want to gratuitously make the format
less reliable to parse by tools, when the main usage _is_ the
application by independent tools.
