As explained in https://bugs.documentfoundation.org/67302
this is the right thing to do in that directory, but cannot
be comitted in isolation. All callers of that function in
all of LibreOffice need to be adapted to the new syntax
of the returned value (that is that the value is now properly escaped). This needs to be done at the same time in all drivers and all places that call this API (+documented in the release notes).

This reverts commit d43f4390.
