git-clone: Support changing the origin branch with -o

Browse source 
Earlier, git-clone stored upstream's master in the branch named 'origin',
possibly overwriting an existing such branch.

Now you can change it by calling git-clone with '-o <other_name>'.

[jc: added ref format check, subdirectory safety, documentation
 and usage string.]

@ -56,6 +56,13 @@ OPTIONS
-n::
No checkout of HEAD is performed after the clone is complete.
-o <name>::
Instead of using the branch name 'origin' to keep track
of the upstream repository, use <name> instead. Note
that the shorthand name stored in `remotes/origin` is
not affected, but the local branch name to pull the
remote `master` branch into is.
--upload-pack <upload-pack>::
-u <upload-pack>::
When given, and the repository to clone from is handled
