Title: Update docs for TRAVIS_BRANCH environment variable

As @floehopper and @rkh discussed yesterday the TRAVIS_BRANCH environment variable is set to the target branch rather than the one being built when building pull requests.

This updates the documentation to reflect this - however the wording is a bit awkward so improvements would be welcomed.
