git branch command is incompatible with bash

Hello!

I hope posting this to this mailing list is okay, this is the first ever mail that I submit to a technical mailing list.

When using the git branch command, git uses a '*' to denote the current branch. Therefore, in bash this:

	$ branchName=$(git branch -q)
	$ echo $branchName

produces a directory listing, because the '*' is interpreded by the shell.

While an (unwieldly) workaround exists:

	$ branchName=$(git symbolic-ref -q HEAD)                                                                            
	$ branchName=${branch##refs/heads/}

it would still be nice, if there were a --current flag, that returned only the current branch name, omitting the star:

	$ branchName=$(git branch --current -q)
	$ echo $branchName
	master
