-n switch not working

[warhansen]

When I try pdfcrack with -n='x' it still tries passwords with less characters than 'x':

pdfcrack -f 001_00327_20180831_1.pdf -n=10 -c 0123456789

If this works correctly the "Current Word" should be 10 characters or more?

Thank you.

I tested now "--minpw=x" works
