Brian Gernhardt 0005702399 git_prompt: print unique detached HEAD abbreviated object name
Simply using cut duplicates (poorly) `git rev-parse --short`

This also restores the ... printed after the abbreviation which
__fish_git_prompt had been missing.

Based on git.git e8f21ca: "bash prompt: print unique detached HEAD
abbreviated object name"
