Show usage string for 'git http-push -h'

Browse source 
http-push already knows how to dump usage if it is given no options, but
it interprets '-h' as the URL to a remote repository:

    $ git http-push -h
    error: Cannot access URL -h/, return code 6

Dump usage instead.  Humans wanting to pass the URL -h/ to curl for some
reason can use 'git http-push -h/' explicitly.  Scripts expecting to
access an HTTP repository at URL '-h' will break, though.

Also delay finding a git directory until after option parsing, so
"http-push -h" can be used outside any git repository.
