+ Pretty-prints the details of a commit. `--pretty`
+ without an explicit `=<format>` defaults to 'medium'.
+ If the commit is a merge, and if the pretty-format
+ is not 'oneline', 'email' or 'raw', an additional line is
+ inserted before the 'Author:' line. This line begins with
+ "Merge: " and the sha1s of ancestral commits are printed,
+ separated by spaces. Note that the listed commits may not
+ necessarily be the list of the *direct* parent commits if you
+ have limited your view of history: for example, if you are
+ only interested in changes related to a certain directory or
+ file. Here are some additional details for each format:
+This is designed to be as compact as possible.
+ AuthorDate: <date & time>
+ CommitDate: <date & time>
+ Subject: [PATCH] <title line>
+The 'raw' format shows the entire commit exactly as
+stored in the commit object. Notably, the SHA1s are
+displayed in full, regardless of whether --abbrev or
+--no-abbrev are used, and 'parents' information show the
+true parent commits, without taking grafts nor history
+simplification into account.
