Subject: git-remote: show all remotes with "git remote show"
X-Git-Tag: v1.5.6-rc0~139^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c4112bb6bbc83708c7b54deac0928e66b4de2302;p=git.git

git-remote: show all remotes with "git remote show"

Many other commands use the "no arguments" form to show a
list (e.g., git-branch, git-tag). While we did show all
remotes for just "git remote", we displayed a usage error
for "git remote show" with no arguments. This is
counterintuitive, since by giving it _more_ information, we
get _less_ result.

The usage model can now be thought of as:

  - "git remote show <remote>": show a remote
  - "git remote show": show all remotes
  - "git remote": assume "show"; i.e., shorthand for "git remote show"
