Re: [PATCH] git-config: document interactive.singlekey requires Term::Readkey

Thanks, but is it true that interactive.singlekey "requries"
Term::ReadKey?

The relevant part of git-add--interactive reads like so:

if ($repo->config_bool("interactive.singlekey")) {
	eval {
		require Term::ReadKey;
		Term::ReadKey->import;
		$use_readkey = 1;
	};
	eval {
		require Term::Cap;
		my $termcap = Term::Cap->Tgetent;
		foreach (values %$termcap) {
			$term_escapes{$_} = 1 if /^\e/;
		}
		$use_termcap = 1;
	};
}

The implementation of prompt_single_character sub wants to use
ReadKey, but can still let the user interact with the program by
falling back to a cooked input when it is not available, so perhaps
a better fix might be something like this:

        if (!$use_readkey) {
        	print STDERR "missing Term::ReadKey, disabling interactive.singlekey\n";
        }

inside the above if() that prepares $use_readkey?

You also misspelled the package name it seems ;-)
