I know. But we are left with three options:

  1. Add "git remote list" with verbose output. This is bad because it
     differs gratuitously from "git remote".

  2. Add "git remote list" with non-verbose output. This is good because
     it means "git remote" is just a shortcut for "git remote list",
     which is consistent with other parts of git. But it is potentially
     bad if "-v" is a better output format.

  3. Add "git remote list" with verbose output, and tweak "git remote"
     to match. This is bad because it breaks backwards compatibility.

The proposal is for (1). I think we agree that (3) is out. The question
is whether (1) or (2) is the least bad.

Branch and tag take "--list". Remote is the odd one out in that its
subcommands do not have dashes. git-stash also takes commands without
dashes (and has a list command), but its default mode is to create a
stash, not to list.

Yeah. Branch and tag need dashed subcommands because otherwise it is
ambiguous with creating tag called "list", functionality that existed
before "--list" was added. Git-remote was defined with subcommands from
day one, so it can get away with it. Git-stash is sort of in the
category as git-remote there, except that "save" can actually take an
argument. So to provide it you can't say "git stash foobar", but instead
have to say "git stash save foobar" (it actually used to allow the
former, but you can imagine the annoyance when you typo "git stash
lsit").
