The 'g' character is not part of the sha1, but just a prefix used by git
describe. The point of this alias is to refer (in email or other
writing) to commits. Obviously just the sha1 would be sufficient, but
the subject and date of the commit gives the reader some context without
them having to plug it into git-show.
