This reverts commit 27e9c5af817147ea1c678769e45e83f2e4b4ae96.
a1a6d4
a1a6d4
Property values already use escaping, so escaping them a second time is
a1a6d4
confusing. It also should be mostly unnecessary: we take care to make property
a1a6d4
values only contains strings which (after the initial escaping) are printable
a1a6d4
and parseable without any futher escaping.
