Match start of method name

[trevorrjohn]

We had an issue where no matches were returned despite there being a string match.

class Foo
  def self.set_result_count; end
end

Foo.set_result
#=> NoMethodError: undefined method `set_result' for Foo:Class

Foo.set_result_c
#=> NoMethodError: undefined method `set_result_c' for Foo:Class

    Did you mean? .set_result_count

It would be desirable for the suggestion to appear if everything matches except the postfix. I am not sure how this would look on shorter method names.

@tjohn Actually it was already implemented (more specifically Jaro-Winkler distance), but it often suggests too many suggestions (see #49). I guess the combination of Levenshtein and Jaro-Winkler distance would be a good fit.

It's hard to make did_you_mean smarter, but the next major version should be coming with a better suggestion algorithm.

Thanks!

I'm closing this issue since a prefix-based spellchecker has been implemented and shipped with v0.10.0. Thanks!
