# Compare a file containing rev-list bitmap traversal output to its non-bitmap
# counterpart. You can't just use test_cmp for this, because the two produce
# subtly different output:
#
# - regular output is in traversal order, whereas bitmap is split by type,
# with non-packed objects at the end
#
# - regular output has a space and the pathname appended to non-commit
# objects; bitmap output omits this
#
# This function normalizes and compares the two. The second file should
# always be the bitmap output.
