Hi,
the --abbrev option doesn't allow a 40 digit SHA1 output.
The following patch fixes this, and uses a IMHO more logical way to
compute the abbrev parameter, so --abbrev=52 will still yield a 40 digit
SHA1.

use constant variable for storing "--abbrev=". Use 40 and
MINIMUM_ABBREV as bounds for --abbrev= argument.
