We don't want to support any language-like flow control in unit files.
It's actually much more of a feature than a limitation that unit files
are *descriptive* and not little programs that run. Things should not
be evaluated at runtime beyond the simple conditions we support.

So no, we don't want anything like macros, pre-processing, or language
constructs in unit files.
