Err, is this really fixed in 2.21? I can't find it anywhere in 2.32.3
(debian unstable)

+-----
+
+I just did a `--dumpsetup` with the current version from the Git repository
+and the default option is
+
+ # use '!'-prefixed preprocessor directives?
+ prefix_directives => 0,
+
+My impression was that this should be enabled by default now. --[[JasonBlevins]]
