Ah. I had hyphens in my filenames. Removing them cleared that error, but
now I get:

warning: Skipping data file with no valid points

I tried a non loop minimal example to ensure it's not a problem with my
datafile:
stats 'file.txt' prefix "file"
plot 'file.txt' every::file_index_max::file_index_max

This works fine.

Is there a way to look at what a command expanded into after the variables
were substituted?
