Gem binary paths with spaces create a problem for bundle exec

[bfad]

If the path to your project has a space in it and you keep your gems in your project, then bundle exec fails when trying to run any binaries. Below is a zsh script that shows the issue. (It looks like it also happens with bash.)

#!/bin/zsh

mkdir -p '/tmp/sp ace/project/'
cd '/tmp/sp ace/project/'
mkdir 'spec/'

cat > Gemfile <<EOF
source 'http://rubygems.org'
gem 'rspec'
EOF

bundle install --path vendor

# Expected behavior: should work
# Observed behavior: errors with rspec not executable
bundle exec rspec

# If you execute the following, you'll see the space isn't escaped
#bundle exec env | grep PATH

Here is my bundle env

This is only an issue when bundle exec is trying to run a command without any additional arguments -- I'm looking into a fix right now :)

I can verify that if I run bundle exec rspec spec then it runs as expected. Thanks for the quick response.
