A missing branch name is the same as HEAD, so:

If you say "no branch name", then it assumes that it's head in your
local and remote repositories.

So it's expected. It also *should* warn about the fact that the remote
repository HEAD does not match. Does it not do that?

Anyway, in general, you should always use a branch-name for "git
request-pull", since you use branches. The "no branch name" is really
only meant for the very original kind of git workflow where you don't
use branches at all. Some people still do that (David Miller seems to
prefer separate repositories over multiple branches, for example), but
it's starting to be unusual.

Also, if your local branch is named differently from your remote one,
you need to use the same format as you would have done for "git push"
to push it out, so you'd do

    git request-pull remote-repo local-branch-name:remote-branch-name

but quite frankly, I wouldn't recommend that workflow. I think it's
too prone to mistakes.

So what I always do on all my repositories is that "origin" ends up
being the public thing, and then I have a separate set of things I
push to.

Now, the reason I do that is that pushing is different from pulling,
not only because of the whole security thing, but because I push to
multiple repos.

So my .gti/config looks roughly like this:

[remote "origin"]
    url = git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
    fetch = +refs/heads/*:refs/remotes/origin/*

[branch "master"]
    remote = origin
    merge = refs/heads/master

[remote "all"]
    url = ra.kernel.org:/pub/scm/linux/kernel/git/torvalds/linux
    url = git@github.com:torvalds/linux.git

and that means that when I pull from my own remote (which I actually
do when I travel - it's hoe I synchronize my laptop and desktop), I
use origin. And when I push, I do "git push all", and it pushes to
both kernel.org and to the github "mirror".

And a plain "git push" simply won't work, which is fine.
