work on more than strings

This would be useful in cockroachdb/cockroach if it could also detect duplicate integers. In particular, we want to use constants for time.Durations in our tests - it'd be nice if this tool provided that check.

You can now use -numbers. It searches for duplicate integers and floats.

Heh, this is sadly too much of a blunt instrument - it picks up very small numbers that aren't worth extracting like if len(args) == 1 {....}. Perhaps a threshold?

[jgautheron]

Just implemented -min and -max, let me know if that helps.
