Revision 91dcdfd3b5331d955cfb60edf8930f1b5c142905 authored by Linus Torvalds on 12 July 2005, 03:44:20 UTC, committed by Linus Torvalds on 12 July 2005, 03:44:20 UTC 
Make "git checkout" create new branches on demand
 
In particular, if we check out something that isn't an old branch, it
now requires a new branch-name to check the thing out into.

So, for example:

	git checkout -b my-branch v2.6.12

will create the new branch "my-branch", and start it at v2.6.12, while

	git checkout master

will just switch back to the master branch.

Of course, if you want to create a new branch "my-branch" and _not_
check it out, you could have done so with just

	git-rev-parse v2.6.12^0 > .git/refs/heads/my-branch

which I think I will codify as "git branch".
