Update the utilities' --help against the accepted options

[evelikov]

While looking at some of the tools, I spotted some discrepancies between the --help vs the actually supported options. Somewhat naively I didn't record where I saw that, although it didn't seem an isolated instance.

Walk through and update them. Should first check if/which deprecated options should be in --help and wheather using the option should bring a deprecation warning on sorts.

Should first check if/which deprecated options should be in --help

I think that will be a case-by-case decision, but most of them I'd say "no, they shouldn't be in the --help"
