Can't handle multiline 'ref statements in the .tf file

[horror-vacui]

tf import returns with an error related to the first line below:

            'ref "Vx.S.1_V1, Vx.S.1_V1, VxBAR.S.Vx.2_V1, VxBAR.S.Vx.2_V1, \
            Vx.S.1_V1, Vx.S.1_V1, VxBAR.S.Vx.2_V1, VxBAR.S.Vx.2_V1, \
            VxBAR.S.Vx.2_V1, VxBAR.S.Vx.2_V1, VxBAR.S.2_V1, VxBAR.S.3_V1, \
            VxBAR.S.Vx.2_V1, VxBAR.S.Vx.2_V1, VxBAR.S.3_V1, VxBAR.S.3_V1"

Unfortunately I am not allowed to share the technology file, but I think I can say so much as that the above line is inside a spacingTables() function/object and also inside in a minCutClassSpacing, which is only defined for vias. The error occurs at the first such minCutClassSpacing block.

The error message:

After I've removed the '' characters and joined the lines together, the techfile was read in, and the layer names & purposes have been recognized.

I've used KLayout 0.26.5 with tf_import 1.0.
