Output format quicks

[jneubert]

Not sure if "quicks" output format is supposed to survive - if not, the following is not relevant.

I would expect that quicks output gives me input statements for https://tools.wmflabs.org/wikidata-todo/quick_statements.php - that means: valid and executable lines according to the specification, perhaps intermingled with other information marked a comment.

The following does not look like commands (in that lines do not start with an item identifier:

$ wdmapper check P227 P2428 -i /opt/repec-ras/var/ras/example2/map/gnd_ras_mapping.test.csv -t quicks
# skipping indirect link 124825109 -> Q? -> psn9

-Q1082503       P227    "170947386"

Since the wfmlabs tool requires TAB (\t) separators and input by copy&paste, it could make sense to mask the TAB delimiter, because tabs may get replaced by blanks when copied over from a terminal window. I used something printable (e.g. "___") in such cases and replaced that with actual TABs in an intermediate step.
