[Pkg-javascript-devel] Bug#884362: node-uglify: --version output format changed

[Thorsten Glaser]

Package: node-uglify
Version: 2.8.29-3
Severity: minor

	tglase at tglase-nb:~ $ uglifyjs --version
	2.8.29

This is after an upgrade. Before, it output:
	uglify-js 2.8.29

There was apparently no change to the node-uglify package itself,
only to some *other* nodejs packages.

Please explain how this comes to be. This broke our build, which
uses the output of “uglifyjs --version 2>/dev/null” to determine
whether 2.x or 3.x was used, to prevent too-new versions (as some
coworkers use Canonical’s software museum together with npm, in‐
stead of getting all dependencies via Debian).

To me, outputting a version number is a simple WriteLn/echo/print{,f}
command. Why and how can this change if a dependency changes? Which
dependency was it, and what else does this change affect?
