git checkout -b origin/mybranch origin/mybranch

Hey all,

  One of my collegues did:

git checkout origin/somebranch

  git complained that they need to specify the name with -b.  So they did:

git checkout -b origin/somebranch origin/somebranch

  Git accepts this with no problems, but boy - all hell broke loose.
Doing a push or pull gave errors, because "origin/somebranch" is now
ambigous (since there is two of them).  They can't even:  "git
checkout -b somebranch origin/somebranch"  anymore, since
"origin/somebranch" is ambigous.  It all got into a mess.

  I've sort it out now, but I'd like to request that git doesn't so
easily let the user shoot themselves in the foot.

  I propose that creating a branch called  "origin/*" or "remotes/*"
gives at _least_ a warning, and preferably an error (overrideable with
--force for people who really really want to do it)
