git branch -a breaks shell when there are many branches

[kgsterneberg]

"git branch -a" breaks my shell if I use it on a repository with many branches. Works one time. Next time result is: git branch -a -bash: /usr/bin/sed: Argument list too long -bash: /usr/bin/ruby: Argument list too long -bash: /usr/bin/git: Argument list too long -bash: /usr/bin/sed: Argument list too long

Complete test:

git branch -a [1] my-branch [2] your-branch ... [6735] some other branch

git branch -a -bash: /usr/bin/sed: Argument list too long -bash: /usr/bin/ruby: Argument list too long -bash: /usr/bin/git: Argument list too long -bash: /usr/bin/sed: Argument list too long

git status -bash: /usr/bin/git: Argument list too long
