iteration not applied to title

[<pl...@pi...>]

Hi,

in experiment with new iteration feature I found it does not seem to be 
applied correctly (ie usefully) to the automatic title in the key

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

unless I explicitly set a title both plots get an identical entry in the 
legend :  "dataset-".date.".dat"

This would seem to render the legend key entries somewhat useless. It 
also seems illogical that it expands the filename to be plotted but does 
not expand the entry in the legend.

Is this an oversight or am I missing some cunningly useful feature?

Best regards, Peter.
