Possible to skip stack frame in src?

[SomeoneWeird]

We have a library we use to massage messages into a format our logs use, lets call it logMe

Something like:

function logMe(data1, data2) {
  bunyan.info(data2, data1)
}

(Obviously a little more complicated than this, but yeah)

This works fine, but screws up the src param when it's enabled, it always points to the line where logMe is defined.

What do you think about being able to pass in a skipSrc param (or named something else, naming is hard) that skips n frames at the top of the list when processing the current stack trace?

Your milage may vary, but instead of wrapping in a function, I just re-used the pointer to bunyan's logging methods. This way there is no extra frame.

Here's an example. (Obviously a little more complicated than this, but yeah.)

export default class CustomLogger {
    constructor() {
        this._bunyanLogger = bunyan.createLogger(...);

        const levels = [
            'fatal',
            'error',
            'warn',
            'info',
            'debug',
            'trace',
        ];

        levels.forEach((level) => {
            this[level] = this._bunyanLogger[level].bind(this._bunyanLogger);
        });
    }
}

You can also .bind() extra variables if you'd like; this._bunyanLogger[level].bind(this._bunyanLogger, 'My custom logging prefix.'), but then you might also want to look at bunyan's child loggers.

Sorry for the stupid delay. This would depend on #460 work (currently high on my list). Sounds like a good feature.
