I am trying to make a git bisect on something that works with the
4.0.0 gem version of Rails and is broken in the `4-0-stable
Normally I would expect a tag called `v4.0.0`, however there is no
such tag in the rails repository.
Oddly enough there is a branch called `4-0-0` (in addition to the
`4-0-stable` branch), but that branch cannot be the source of the gem
either, since the file `RAILS_VERSION` contains
Any help is appreciated.
