For the archive, I worked around this problem by solving it a different way.  Instead
of changing the fish_prompt function, I defined a fish_prompt event handler to print
the extra blank line:

function fish_prompt_handler --on-event fish_prompt
    echo
end

This gives me the blank line before each prompt, and for whatever reason it doesn't
interfere with syntax highlighting as I type.
