It turns out shell.el is deliberately doing this, as I expected. The regexps
they use for the matching are in shell-font-lock-keywords. They don't work
that well (e.g. matching "--whatever" in the middle of a line, but not at
the beginning) and I find the colors distracting, so I just disabled the
coloring with (setq shell-font-lock-keywords nil).
