Provide option for parse error handler command prepending

[Radiergummi]

Currently, the command line is prepended to the error message in src/index.js L332-L340:

.catch(err => {
            // jsdoc err might not be very useful when some arguments are
            // invalid. so, we'll prepend the full command, in case of an
            // error and re-throw.
            const cmd = 'jsdoc ' + args.join(' ');
            err.message = err.message + ' \nExecuted JSDoc Command: ' + cmd + '\n'
                + 'with JSON configuration: ' + JSON.stringify(conf || {});
            throw err;
        })

Would it be possible to provide an option to turn this off? That's more of a debugging issue 😊

Sure but what's your use case? If you don't want it to throw, you'd still catch it. So you want to see the error but not the extra information in the message?

I'm working on a documentation framework called Phoenix that splits reading, parsing and writing in separate steps, basically. I need all parser error messages in a digestible format, so the command line is simply not relevant there. Currently, I'm using error.message.replace( /Executed JSDoc Command: [\s\S]*/, '' ), but I'm a little uncomfortable with a hard coded string in there that might change.

Alright. Added in v2.0.1
Let me know if this works for you.

This is perfect, thank you. I'll make sure to credit you and this project in the README 😊
