Thanks for documenting this, as the sed was rather hard to read:

I wonder if we can make it simpler.
In perl I'd probably just replace the whole string with the equivalent
number of spaces, like:
perl -pe 's/^\^\S+/" " x length($&)/e'
but I suppose some would consider that pretty magical, too. It might be
simpler still to just avoid testing leading whitespace:
sed 's/^\^[0-9a-f]* *//' <full >expected &&
sed 's/^ *//' <actual >actual.stripped &&
test_cmp expected actual.stripped
but perhaps the indentation is a useful part of what we're testing.
