Issue Description

autocomplete on branches when a branch is checkout to a Worktree

If I'm working in my master branch and I've checked out my Development branch to another worktree folder, I cannot auto complete on a git merge because git branch --no-color puts a + symbol in front of the branch.

  Branch1
+ Development                     
+ Release                         
* master                          

The auto complete needs to ignore this leading plus when choosing the branch names. I cannot do git merge D<tab> anymore
