It strikes me as really odd that a core developers like yourself
hasn't tried to justify/explain why push works as it does.

As I am trying to convince our dev. group here to move to git instead of subversion, I
need to learn how git works. Now I have gotten to the push function and I need
to know what can be done with push and how, pitfalls too. As I go along I find behavior
that I find odd and report these to the list.

 git push <repo> v2.6.23:refs/heads/linus
will make a tag look like a branch

 git push <repo> linus:linus
won't let me create the remote branch linus but
 git push <repo> linus
will

 git push <repo> :linus
OOPS, now I just deleted remote branch linus, no warning
 
 git push <repo> linus:refs/head/linus
creates a branch that is invisible(wont show in git branch -a)

 git push <repo> linus:refs/heads/newbranch
creates remote branch newbranch, but you have to know the magic words
refs/heads/ to do it.

Se what I mean?

No it doesn't. If someone else in my group wants to create a branch they
might do the same mistakes as I did.
