Re: [PATCH] git-submodule: Error messages from 'git describe' shouldn't end up on the terminal

> As of now a failure to locate the closest tag to a commit (e.g because there is
> no tag in the repository) is handled explicitly by displaying an 'undefined' tag
> error message. However when git describe fails it will still display an
> undesirable  "fatal: cannot describe SHA1" message. This patch hides that
> message as git-submodule has an alternative and explicit error handling method
> in place for this situation
