# Header folding
#
# Header folding is complex, with lots of rules and corner cases.  The
# following code does its best to obey the rules and handle the corner
# cases, but you can be sure there are few bugs:)
#
# This folder generally canonicalizes as it goes, preferring the stringified
# version of each token.  The tokens contain information that supports the
# folder, including which tokens can be encoded in which ways.
#
# Folded text is accumulated in a simple list of strings ('lines'), each
# one of which should be less than policy.max_line_length ('maxlen').
