Bug#852330: dia: dia --export to svg adds junk to end

[Lars Wirzenius <liw@qvarnlabs.com>]

Package: dia
Version: 0.97.3+git20160930-5
Severity: normal

Dear Maintainer,

I have a .dia file that I need to convert to SVG which I do from the
command line:

    dia --export=/dev/stdout --filter=svg auth.dia

This adds the following line to the end of the output:

    auth.dia --> /dev/stdout

This breaks using the output in many SVG-capable programs. I can
easily filter it out but it'd be nice to not have to.

Thanks.
