Use saner defaults
So that most of the time users won't need to use any switches. --pretty-print has been inverted into jq's --compact-output, and --auto-id has been replaced with barely, if-at-all useful --null-as-id.

Usage
|

~~~~~
|
||||
Three things may appear on the internal command line, in a sequence. The first
|
||||
one must always be the name of the JSON-RPC method to call, as a bare word,
|
||||
separated from the rest by white space. Following that, you may enter two kinds
|
||||
of JSON values. If it is a string, a number, or a null value, it is taken as
|
||||
the "id" to use for the request. If it is an object or an array, it constitutes
|
||||
the method parameters. Booleans may appear in neither.

If it is a string or a number, it is taken as the "id" to use for the request,
|
||||
which would be chosen for you automatically if left unspecified. Finally,
|
||||
a null value indicates that the request should be sent as a notification,
|
||||
lacking the ID completely. Booleans cannot be used for anything.
|
||||
|
||||
The response to the method call may be piped through external commands, the same
|
||||
way you would do it in a Unix shell.

Choose message IDs automatically, in an increasing sequence. Normally you
