Funny indentation?

Unfortunate.  KEEP_UNKNOWN is unwieldy, but it is no worse than the
original.  We do not have options that are common to all "git reflog"
subcommands, so the first token after "git reflog" being anything
that begins with "-" is a sign that the default "show" command is
being asked for.

OK.

Looking good.
