Fish shell tab completions favour Git branches?

In the root of my project I have a directory called features. I also have a Git branch called origin/feature-add-coupon-code-to-report.

When I do git co fe<TAB> the Git branch is matched and completed to git co origin/feature-add-coupon-code-to-report which seems strange to me.

Shouldn't the local directory be matched before the branch give that feature is not present at the start of the branch name?

If I type 3 or more characters then it completes to git co features/.

What is the expected behaviour?

Ruby yield as a default parameter

Learnt this from Avdi Grimm's Ruby Tapas

def content_for(tag, content = yield)
  "<%s>%s</%s>" % [tag, content, tag]
end

content_for("p", "hi")
=> "<p>hi</p>"

Idea from @sferik's talk at Baruco 2014

Implicit blocks with yield are faster than explicit blocks with #call.

require 'benchmark/ips'

def explicit(&block)
  block.call
end
