address@hidden: Bug#808917: m4: FTBFS: FAIL: test-update-copyright.sh]

[Santiago Vila]

Greetings.

I've received this report from the Debian bug system.

Fortunately, it has been easy to diagnose and fix: New perl (5.22)
makes test-update-copyright.sh to give a deprecation warning because
there are unescaped braces in build-aux/update-copyright.
The warning message makes the test to fail, which in turn
makes the Debian package build to fail.

The attached patch seems to fix this.

Thanks.
