You abbreviate the commit name to 7 characters. This is too short for 
certain repositories to remain unique. In my group, it is customary to 
abbreviate to 8 charaters. This reduces the usefulness for my use. If 
you don't want to make this a configuration I would suggest to aim for a 
longer commit name as it is simpler to delete excess letters after 
pasting than to add back the missing ones.

Except for this, I like the idea.
