versions of git will have a `post-merge` hook that should work for
this purpose.
+## Fix for error on git pull origin
+
+Error message when running git pull origin:
+
+ You asked me to pull without telling me which branch you
+ want to merge with, and 'branch.master.merge' in
+ your configuration file does not tell me either. Please
+ name which branch you want to merge on the command line and
+ try again (e.g. 'git pull <repository> <refspec>').
+ See git-pull(1) for details on the refspec.
+
+ If you often merge with the same branch, you may want to
+ configure the following variables in your configuration
+ file:
+
+ branch.master.remote = <nickname>
+ branch.master.merge = <remote-ref>
+ remote.<nickname>.url = <url>
+ remote.<nickname>.fetch = <refspec>
+
+ See git-config(1) for details.
+
+The solution is to run this command in your srcdir:
+
+ git config branch.master.remote origin
