bin/spring doesn't work when specifying a github path in the Gemfile

[jmuheim]

When having not the original gem loaded in the Gemfile:

  gem 'spring', github: 'guard/spring',
                branch: 'listen2'

...then the bin/spring (that was patched using bundle exec spring binstub --all) doesn't work, because the REGEX doesn't match GIT (only GEM):

if match = Bundler.default_lockfile.read.match(/^GEM$.*?^    spring \((.*?)\)$.*?^$/m)

I changed it to this:

if match = Bundler.default_lockfile.read.match(/^GEM|GIT$.*?^    spring \((.*?)\)$.*?^$/m)

...which seems to solve this specific problem. But when trying to run spring, it's not found, as it isn't recognised as a gem (I guess):

$ spring
/Users/josh/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:298:in `to_specs': Could not find 'spring' (= 1.1.2) among 176 total gem(s) (Gem::LoadError)
    from /Users/josh/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:309:in `to_spec'
    from /Users/josh/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_gem.rb:53:in `gem'
    from /Users/josh/Documents/Work/MuheimWebdesign/synaesthesia/bin/spring:15:in `<main>'

I have to use bundle exec to make it work:

$ bundle exec spring
Version: 1.1.2
...

As guessed, the gem is not found:

gem list | grep spring
# (nothing)

Bundle list:

$ bundle | grep spring
Using spring (1.1.2) from git://github.com/guard/spring.git (at listen2)

Is this expected behavior? Is there anything to fix? Just wanted to point this out here, maybe it's important info.

It's not supported. I've clarified in the above commit.
