lnav script doesn't see value coming via rewriter

[ostrolucky]

I'm trying to use rewriter like so

"context": {"kind": "json", "rewriter":  "|format"},

If my format.lnav (without headers) is

:echo foo

It works and replaces context with foo.

This works as well.

;SELECT :context as context

It displays actual context

However, this doesn't

;SELECT :context as context
:echo $context

lnav just doesn't display anything. I'm not sure how I can work with the value there. I also tried to pass it like so

"context": {"kind": "json", "rewriter":  "|format ${context}"},

with this script

:echo $1

with same results (no value)

This looks like a bug. I've created issue #1218 and pushed a change that should fix the problem.
