Save branches before delete them truely

If delete branch once, recovering that is very painful. You have to trace Reflog mainly consist of hashsum. Would you use trash-box? Using this command, the branch doesn't delete really and appended "trash/" prefix.

How to use

If you want to delete "branch-A",

$ git trash-branch branch-A

Instead of deleting branch-A, this command move "branch-A" to "trash/branch-A".

If you want to restore branch-A, simply

$ git branch -m trash/branch-A branch-A

When you decide to delete it completely,

$ git -(d|D) trash/branch-A

By using zsh alias function, git branch command can list only not-trashed branches. For more details, See Installation section.
