[PATCH 08/13] show-branch: mark --reflog option as NONEG

[Jeff King <peff@peff.net>]

Running "git show-branch --no-reflog" will behave as if "--reflog" was
given with no options, which makes no sense.

In theory this option might be used to cancel an earlier "--reflog"
option, but the semantics are not clear. Let's punt on it and just
disallow the broken option.

On most of these I tried to decide whether there was a sensible
behavior, and actually do the fix. But I have to admit I have no idea
how "show-branch -g" is supposed to work, which is the main reason I
punted here. If somebody cares enough to write a patch, they can
supersede this (but we should do something, because the current behavior
is nonsense).
