49-g, \--walk-reflogs::
50 Show commits as they were recorded in the reflog. The log contains
51 a record about how the tip of a reference was changed.

57--full-diff::
58 Without this flag, "git log -p <paths>..." shows commits that
59 touch the specified paths, and diffs about the same specified
60 paths. With this, the full diff is shown for commits that touch
61 the specified paths; this means that "<paths>..." limits only
62 commits, and doesn't limit diff for those commits.
