ls-remote: add support for showing symrefs
Sometimes it's useful to know the main branch of a git repository without actually downloading the repository. This can be done by looking at the symrefs stored in the remote repository. Currently git doesn't provide a simple way to show the symrefs stored on the remote repository, even though the information is available. Add a --symref command line argument to the ls-remote command, which shows the symrefs in the remote repository. While there, replace a literal tab in the format string with \t to make it more obvious to the reader.
