First, I think the style should just use
<substitute>
<text macro="editor" />
<text macro="translator" />
<text macro="anon"/>
</substitute>
</names>
which eliminates the need for the conditional in the "anon" macro.
I don't think we have ever discussed what the behavior of the conditional
should be in case of a suppressed variable, and I think a case can be made
for both choices. Assuming that suppressed variables are "unset" in
conditionals gives a bit more flexibility in coding style logic, but
ignoring suppression would make styles easier to debug.
