[PATCH] parse-options.c: display subcommands properly in check_typos

["aubrey via GitGitGadget" <gitgitgadget@gmail.com>]

From: aubymori <aubyomori@gmail.com>

Before this, mistyping a subcommand with one dash (e.g. `git stash -list`)
would display a message telling the user to try it with two dashes.
Since subcommands are parsed with no dashes, this is incorrect and simply
results in the help message for that command being shown.

This commit changes check_typos to check the command type and display a
proper message for subcommands.
