describe: fix --exclude, --match with --contains and --all

git describe --contains acts as a wrapper around git name-rev. When operating with --contains and --all, the --match and --exclude patterns are not properly forwarded to name-rev as --exclude and --refs options. This results in the command silently discarding match and exclude requests from the user when operating in --all mode. We could check and die() if the user provides --contains, --all, and --match/--exclude. However, its also straight forward to just pass the filters down to git name-rev. Notice that the documentation for --match and --exclude mention the --all mode. It explains that they operate on refs with the prefix refs/tags, and additionally refs/heads and refs/remotes when using --all. Fix the describe logic to pass the patterns down with the appropriate prefixes when --all is provided. This fixes the support to match the documented behavior. Add tests to check that this works as expected. Reported-by: Tuomas Ahola <taahol@utu.fi> Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
