---repo=<repo>::
-	When no repository is specified the command defaults to
-	"origin"; this overrides it.
+--repo=<repository>::
+	This option is only relevant if no <repository> argument is
+	passed in the invocation. In this case, 'git-push' derives the
+	remote name from the current branch: If it tracks a remote
+	branch, then that remote repository is pushed to. Otherwise,
+	the name "origin" is used. For this latter case, this option
+	can be used to override the name "origin". In other words,

+git push public         #1
+git push --repo=public  #2
+--------------------------
++
+is that #1 always pushes to "public" whereas #2 pushes to "public"
+only if the current branch does not track a remote branch. This is
+useful if you write an alias or script around 'git-push'.
