# The annotated listing is generated as follows: A file of annotations
# is created based on a file that contains the same number of lines as
# the source file, but all lines are empty.
#
# Then, for each patch that modifies the source file, a diff without
# context is generated (-U0 or -C0 would do, but I've picked -e).  In
# that diff, all line additions are replaced with the identifier of the
# patch (1, 2, ...). These patches are then applied to the empty file.
#
# Finally, the annotations listing is merged with the source file line
# by line.

Ahh, a leftover, thanks.
