and I advanced the liberal a bit more. ;)
So maybe we'd be looking that no 'detached HEAD' occurs?
test_i18ngrep ! "'detached HEAD'" actual
I think testing that we do not give out advice (i.e. behave the same as if
not giving out advice) is best tested to just compare the output to
the output of "git -c advice.detachedHead=false ...", which is what I do here.
This seems to be future proof to me no matter how we reword the advice or
the actual message on checkout?
Thanks,
