[PATCH] git-{parse-remote,pull}: throw away stderr of git-symbolic-ref

[Jeff King <peff@peff.net>]

We look up the destination of the HEAD symref in order to get the
default remote and merge head for the current branch. However, if we
have a detached HEAD, there is no current branch. We handle this
situation by looking up branch..remote, which is empty.
Unfortunately, git-symbolic-ref complained to stderr, potentially
scaring users.
