+%
+% 2. The overall rule is that symbols representing physical quantities (or
+% variables) are italic, but symbols representing units, or labels, are
+% roman. [...]
+%
+% 3. The above rule **applies equally to letter symbols from both the Greek
+% and the Latin alphabet**, although authors often appear to resist
+% putting Greek letters into italic.

+% [emphasis by the author]. In contrast, the standard LaTeX style treats Greek
+% symbols as invariant operators with lower case italic and upper case upright.
