Fix command line option -h

[nichtich]

Calling oq -h prints the help screen of jq -h and hangs. Both oq --help and oq -h should emit the same output. In my opinion the output of jq -h minus the first three lines should be appended to the current output of oq --help.

This was originally by design as I wanted to give a way to access the help of jq as well as oq. But simply combining them might be the better implementation.

Usage: oq [--help] [oq-arguments] [jq-arguments] jq_filter [file [files...]]
    -h, --help                       Show this help message.
    -i FORMAT, --input FORMAT        Format of the input data. Supported formats: json, yaml.
    -o FORMAT, --output FORMAT       Format of the output data. Supported formats: json, yaml, xml.
    --indent NUMBER                  Use the given number of spaces for indentation (JSON/XML only).
    --xml-root ROOT                  Name of the root XML element if converting to XML.
    --no-prolog                      Whether the XML prolog should be emitted if converting to XML.

	jq is a tool for processing JSON inputs, applying the
	given filter to its JSON text inputs and producing the
	filter's results as JSON on standard output.
	The simplest filter is ., which is the identity filter,
	copying jq's input to its output unmodified (except for
	formatting).
	For more advanced filters see the jq(1) manpage ("man jq")
	and/or https://stedolan.github.io/jq

	Some of the options include:
	 -c		compact instead of pretty-printed output;
	 -n		use `null` as the single input value;
	 -e		set the exit status code based on the output;
	 -s		read (slurp) all inputs into an array; apply filter to it;
	 -r		output raw strings, not JSON texts;
	 -R		read raw strings, not JSON texts;
	 -C		colorize JSON;
	 -M		monochrome (don't colorize JSON);
	 -S		sort keys of objects on output;
	 --tab	use tabs for indentation;
	 --arg a v	set variable $a to value <v>;
	 --argjson a v	set variable $a to JSON value <v>;
	 --slurpfile a f	set variable $a to an array of JSON texts read from <f>;
	See the manpage for more options.

Is what I got ATM.

I'm happy with it.

Great! I'd only replace the tabs in jq's help with 4 spaces but that's cosmetics.
