* Proof of concept treating env vars as Values * Refactor env var collection and method name * Remove unnecessary pub * Move env translations into a new file * Fix LS_COLORS to support any Value * Fix spans during env var translation * Add span to env var in cd * Improve error diagnostics * Fix non-string env vars failing string conversion * Make PROMPT_COMMAND a Block instead of String * Record host env vars to a fake file This will give spans to env vars that would otherwise be without one. Makes errors less confusing. * Add 'env' command to list env vars It will list also their values translated to strings * Sort env command by name; Add env var type * Remove obsolete test
