Considering that we still just output with a tenth of a percent granularity, I'd suggest just continuing with using permille internally - including for the limit.

So instead of actually using floating point, just parsing a single digit worth of fractional percent would be beautiful. IOW, being able to say

  --dirstat=1.5

to give a 1.5% cut-off point would be really nice - but then internally just saying "15 permille" and using integers all the way?

Doing all the fake floating point by hand also obviously then avoids the whole LC_NUMERIC locale issue.
