[PATCH] rev-list: heed --abbrev-commit option

Currently, rev-list has a default of "0" for abbrev which means that
switching on abbreviations with --abbrev-commit has no visible effect,
even though the option is documented.

Set abbrev to DEFAULT_ABBREV so that --abbrev-commit has the same effect
as for log.

I'm actually wondering why log and rev-list don't share the relevant
part of that code.
