Summary0000200: When given a bad option on the command line print what is usually displayed with -help
DescriptionWhen a bad option is given on the command line, currently it comes back with something like:

ERROR: Option matching -scale_factor not found in command line top-level context
caught exception ERROR: Option matching -scale_factor not found in command line top-level context

Wouldn't it be nice it came back with that error and then (formated in fixed with font of course):


Usage:

../../../bin/benchmark.postgres.linuxclangrelease [options]

Options: [Specify on command line or in @file]

Showing only relevant options...

 There are (at least) two types of bad options:

A) Correct but insufficiently specific option (did you mean -packing:repack_only, or -somethingelse:repack_only?)

B) Never-correct options (-this_option_does_not_exist)

We only want to print help for B; for A it already prints a nice message requesting the user disambiguate their choice (and what the unambiguous choices are).
