[PATCH] Add `-u` short option for `git pull`

From: Julien Jerphanion <redacted>

Add the short form `-u` as an alias for `--set-upstream`
in `git pull`, similarly to `git push` which supports both forms.

This allows users to use `git pull -u <remote> <branch>` as a
shorter alternative to `git pull --set-upstream <remote> <branch>`.

One test is included to verify that the short form works
correctly and set the upstream configuration as expected.
