The change in #4441 broke the handling of the `elsif`s due to the change in logic. As every block here has a `next` there's no need to do an `elsif` in here at all. Additionally, reorder the conditions in here so you get an appropriate message depending on what you're trying to do. Finally, tweak some of the messaging to remove things that are ignored and tell people correct commands to run to link things.

#: is done automatically when you install formulae but can be useful for DIY

#: If `--overwrite` is passed, Homebrew will delete files which already exist in

#: the prefix while linking.

#: If `--dry-run` or `-n` is passed, Homebrew will list all files which would
|

#: be linked or which would be deleted by `brew link --overwrite`, but will not
|
|
#: actually link or delete any files.
|
|
#:
|
|
#: If `--force` (or `-f`) is passed, Homebrew will allow keg-only formulae to be linked.
