# Compare a file containing rev-list bitmap traversal output to its non-bitmap

# 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.
