When the user is using the 'upstream' mode, these commands:
$ git push
$ git push origin
would find the 'upstream' branch for the current branch, and then
push the current branch to update it. However, pushing a single
branch explicitly, i.e.
$ git push origin $(git symbolic-ref --short HEAD)
would not go through the same ref mapping process, and ends up
updating the branch at 'origin' of the same name, which may not
necessarily be the upstream of the branch being pushed.
In the spirit similar to the previous one, map a colon-less refspec
using the upstream mapping logic.
Note that this is deliberately done after the logic to map refspec
via the remote.$name.push configuration did not find any. This is
because most of those that employ a simple 'upstream' mode do not
have the push refspec, and checking with remote.$name.push refspec
first will allow it to be used as a mechanism to override the usual
'upstream' push mapping (which is primarily useful for centralized
workflow) by those who want to use a triangular workflow.
