Fugitive help inconsistent with usage of `[]` and `{}`

While reading the Vim fugitive help I stumbled upon the :G and :Git commands first. See:

Lines 19 to 22 in 4f59455

    
           :G [args]               Same as :Git, but two characters shorter. 
        
                                                           *:Git* 
        
           :Git {args}             Run an arbitrary git command and display any output.

If :G is the same as :Git why would there be a difference between optional and required args. If my reading of https://vimhelp.org/intro.txt.html#notation is correct then [] is optional and {} means required.

I started preparing a patch but later saw [:Git (with no arguments)](

vim-fugitive/doc/fugitive.txt

Line 51 in 4f59455

:Git With no arguments, bring up a summary window vaguely

) and decided to just report this here. I suggest moving this :Git (with no arguments) closer to the top (near :G and :Git) or simply combine them.

Perhaps review other usages as well.

	:G [args] Same as :Git, but two characters shorter.

	:Git
	:Git {args} Run an arbitrary git command and display any output.
