[PATCH 3/3] examples/commit: use --abbrev for commit summary

[Jonathan Nieder <jrnieder@gmail.com>]

After v1.7.1.1~17^2~3 (pretty: Respect --abbrev option, 2010-05-03),
plumbing users do not abbreviate %h hashes by default any more.

Noticed while investigating the bug fixed by v1.7.1.1~17^2
(commit::print_summary(): don't use format_commit_message(),
2010-06-12).

Again, sorry for the trouble.

Maybe diff-tree should always abbreviate the format %h.  That would
make the Parents: line and %p format produce different result when
the --abbrev option is not supplied.

I could go either way.
