- '%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`).
- '%gn': reflog identity name
- '%gN': reflog identity name (respecting .mailmap, see
linkgit:git-shortlog[1] or linkgit:git-blame[1])
respecting the `auto` settings of the former if we are going to a
terminal). `auto` alone (i.e. `%C(auto)`) will turn on auto coloring
on the next placeholders until the color is switched again.
-- '%m': left, right or boundary mark
+- '%m': left (`<`), right (`>`) or boundary (`-`) mark
- '%n': newline
- '%%': a raw '%'
- '%x00': print a byte from a hex code
