Show branches list (which branches contains commit) on commit page


Shown in the first screenshot:
![commit-box when the page loads](http://puu.sh/4SZAf.png)

it looks like commit-box when the page loads. 

For example:
In any project there default_branch ( branch defaults to the first commit to the repository and can be changed later in the project settings ). If a commit in a branch that is set as the "_default branch_" - that is displayed:

"Exist in `default branch`, `and in other branches count branch(es)`". 

What stood out in the text `so` - a links . 
When you click on `and in other branches count branch(es)` - immediately displays a list of links to other branches on the spot phrase `and in other_branches_count branch(es)`.

If the default branch is not contains commit in  - then the first branch from the list of branches, which include a commit displayed in place `default branch`.
