Adds supports for branches called "feature/this_and_that" which are perfectly fine and used by gitflow approach.

The original split is doing:

ref/master/feature/this_and_that -> causing that "feature" is selected as branch name, rather than "feature/this_and_that"

Note: Adapted from pull request #8 by cypreess.
