[PATCH] reflog: Usage documentation cleanup

[PATCH] reflog: Usage documentation cleanup

[Nelson Elhage]

* Make git-reflog.txt and the builtin usage text consistent.
* Make 'git reflog expire' not claim that 'show' takes the same
  arguments as 'expire'.
* Document -n as an alias for --dry-run for the expire and delete
  subcommands.

Thanks to Jeff King and Erik Faye-Lund for both pointing out that 'git
reflog expire' is probably wrong to be documenting the 'show' command
in the first place, which makes this cleanup much saner.
