Subject: [PATCH] Revert "bus: when dumping string property values escape the
 chars we use as end-of-line and end-of-item marks"
MIME-Version: 1.0

This reverts commit 27e9c5af817147ea1c678769e45e83f2e4b4ae96.

Property values already use escaping, so escaping them a second time is
confusing. It also should be mostly unnecessary: we take care to make property
values only contains strings which (after the initial escaping) are printable
and parseable without any futher escaping.

Before revert:
$ systemctl list-dependencies 'dev-mapper-luks\x2d8db85dcf\x2d6230\x2d4e88\x2d940d\x2dba176d062b31.device'
