doc/pretty-formats: explain shortening of %gd

The actual shortening rules aren't that interesting and
probably not worth getting into (I gloss over them here as
"shortened for human readability"). But the fact that %gD
shows whatever you gave on the command line is subtle and
worth mentioning. Since most people will feed a shortened
refname in the first place, it otherwise makes it hard to
understand the difference between the two.

- '%GK': show the key used to sign a signed commit
- '%gD': reflog selector, e.g., `refs/stash@{1}` or
`refs/stash@{2 minutes ago`}; the format follows the rules described
for the `-g` option
- '%gd': shortened reflog selector, e.g., `stash@{1}` or
`stash@{2 minutes ago}`
for the `-g` option. The portion before the `@` is the refname as
given on the command line (so `git log -g refs/heads/master` would
yield `refs/heads/master@{0}`).
- '%gd': shortened reflog selector; same as `%gD`, but the refname
portion is shortened for human readability (so `refs/heads/master`
becomes just `master`).
