When using python-mode for Emacs, if you elect to "Comment Region"
then double-pound signs are inserted.  If you elect to "Uncomment
Region" then only those lines beginning with a double-pound are
uncommented.  So perhaps the lines are highlighted differently on the
assumption that double-pound lines contain "disabled" code.
