Abbreviating ids makes 'git cherry -v' more useful, since you can see more
of the commit message summary:
git cherry -v --abbrev | less -S
Signed-off-by: Jeff Epler <jepler@xxxxxxxxxxxxxx>
---
Compared to the last patch, this adds to the bash completion, improves
doc consistency, and uses find_unique_abbrev to shorten commit ids.
Thanks to Markus Heidelberg for feedback.
