sqlcmd shouldn't show the full set of flags when the user doesn't provide an argument parameter

[shueybubbles]

EG ODBC

16:30:56.64 e:\git>sqlcmd -w
Sqlcmd: '-w': Missing argument. Enter '-?' for help.

And go-sqlcmd:

16:59:19.21 e:\git\go-sqlcmd>.\sqlcmd -w
Error: flag needs an argument: 'w' in -w
Usage:
   [flags]
<followed by every flag of which there are dozens>

The problem is it ends up scrolling the command prompt so far that I can't see what parameter I didn't provide.

Can we switch to only showing the full set of flags when the user passes -? , and giving a reminder to use -? when an argument is missing?
