Thanks, so bug rather than feature. Not a major problem but I thought 
I'd flag it.

Oddly if I put the same thing as title it does get expanded.

  plot for [date in "1881 1883"] "dataset-".date.".dat" tit 
"dataset-".date.".dat"

Just seems rather pointless (and verbose) repetition to achieve what it 
standard behaviour without iteration. Probably a detail that got missed.

regards.
