[Help-source-highlight] [review] JSON language implementation

[muji]

Hello,

Thanks for `source-highlight`, it is fast and easy to customize.

I am working on a tool that required highlighting of JSON documents printed to a terminal so I wrote a JSON language implementation[1] and style file[2].

It appears to function correctly but I would appreciate it if you could review and if it is deemed good enough merge into the next release?

It handles escaped strings correctly, ie:

{

"string": "my \"quoted\" value"

}

I wanted to be able to differentiate elements at a granular level so have introduced some JSON specific style names:

* keyquote - Quotation marks for keys

* valquote - Quotation marks for string values

* colon - The colon delimiter

* key - The string between key quotes

The number handling is taken from number.lang and can be replaced with an include of number.lang if you wish to merge this language definition.
