- '%d': ref names, like the --decorate option of linkgit:git-log[1]
- '%e': encoding
- '%s': subject
+- '%f': sanitized subject line, suitable for a filename
- '%b': body
+- '%gD': reflog selector, e.g., `refs/stash@\{1\}`
+- '%gd': shortened reflog selector, e.g., `stash@\{1\}`
+- '%gs': reflog subject
- '%Cred': switch color to red
- '%Cgreen': switch color to green
- '%Cblue': switch color to blue
- '%n': newline
- '%x00': print a byte from a hex code
+NOTE: Some placeholders may depend on other options given to the
+revision traversal engine. For example, the `%g*` reflog options will
+insert an empty string unless we are traversing reflog entries (e.g., by
+`git log -g`). The `%d` placeholder will use the "short" decoration
+format if `--decorate` was not already provided on the command line.

The 'tformat:' format works exactly like 'format:', except that it

+In addition, any unrecognized string that has a `%` in it is interpreted
+as if it has `tformat:` in front of it. For example, these two are
+equivalent:

+---------------------
+$ git log -2 --pretty=tformat:%h 4da45bef
+$ git log -2 --pretty=%h 4da45bef
