Oh, that's very interesting. Yep, changing font "fixed" the problem.

It's a puzzle why someone thought would think that this would be a good way
for the rendering engine to work. I can think of a few of reasons for it NOT
to behave this way, and none for why it's a good idea.

I'll have to dig in and see if there's a way to turn it off. I'll look at the
details of the font as well; I'm not at all sure what exactly is telling TB
"if you see two consecutive "less-than" signs, then render them as a single
"much less than" character. No other program seems to be doing it, so it seems
to be a TB decision somewhere; but since it seems to be font-dependent, TB
must (presumably) be looking at some characteristic of the font before
deciding to make the substitution. Very strange.

Thanks for the suggestion that it might be dependent on the font.
