This is still the same cryptic comment we have in the

Suggestions?
...well, I don't entirely understand the problem it's
fixing, which is why I'm asking for a better comment :-)
Heh. Fair enough. How about
/* The address covered by the breakpoint must be included in
[tb->pc, tb->pc + tb->size) in order to for it to be
properly cleared -- thus we increment the PC here so that
the logic setting tb->size below does the right thing. */
There are two edge cases that cause the problem with clearing that
could be described, but I think that the comment becomes too bulky, as
well as confuses the situation for someone cutting-and-pasting the
logic to a new port.
