# Clean up html2text's output.  html2text is pretty good at the
# impossible job of converting HTML to readable flat text, but has its
# own peculiarities.  In particular, it tends to generate either too
# few or too many blank lines, depending on how it's been configured.
# Simplest fix is is to configure it to err on the side of too many
# blank lines, then suppress the extraneous ones.
#
# We might add other fixups here later, but this will suffice for now.
