is_file option not working for ask

[elliotcm]

Hello. As far as I can tell, the is_file option for ask is not working, perhaps just on my local environment, but I'm not sure how to debug further.

I've created a minimal test, and confirmed that I can't tab complete either files in CWD or even starting with /

file_test.rb:

require "rubygems"
require "cli/ui"

file = CLI::UI.ask("A file question", is_file: true)
puts "File exists? #{File.exist?(file)}"

Some system/version information (I've [redacted] a few bits):

% gem list cli-ui

Reline.completion_proc in ./lib/cli/ui/prompt.rb appears to not function.
