How about deriving the --version output from the copyright notice, for
those programs that consist of a single file and that are not written in C?
Like this:
diff --git a/build-aux/run-test b/build-aux/run-test
index 94ef7fd912..0b13ed4d59 100755

Advantage: Zero maintenance cost, as we rely on 'update-copyright' for the
copyright notice.
Disadvantage: It's a violation of the boundary between program code and
meta-information.
What do you think? Should we do this?
