Subject: Make git-show-branch options similar to git-branch.
X-Git-Tag: v1.5.0-rc0~28
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f49006b0c79bb74bc500a9a3a883e929fa0f803e;p=git.git

Make git-show-branch options similar to git-branch.

Branch has "-r" for remote branches and "-a" for local and remote.
It seems logical to mirror that in show-branch.  Also removes the
dubiously useful "--tags" option (as part of changing the meaning
for "--all").
