+Testing metadata outputs with internal quotes for the curate command.
+Running the `passthru` subcommand since it does not do any data transformations.
+
+Create NDJSON with internal quotes
+
+  $ cat >records.ndjson <<~~

+
+Test passthru with output to TSV.
+This should not add any quotes around the field with internal quotes.

+  sequence_A\tSRC VB "Vector", Molecular Biology of Genomes (esc)
+
+Run the output TSV through augur curate passthru again.
+The new output should still be identical to the first output.
