/branchB
/commit<SHA1>

Test code:

A possible and tested solution for merging branchB into our checked-out branchA:

...ngs). It's fine with literal values, but doesn't resolve model properties (tested with Ember 1.0.0-rc.8 and Handlebars 1.0.0), and registerBoundHelper can't deal with Handlebars syntax. The workaround is to create a custom view: stackoverflow.com/questions/18005111/…
