mxcl/homebrew — Issue #8287: watch formula doesn't recognize -d option

After installing the watch formula via brew and trying to run some of the commands mentioned in the man file, the -d option consistently does not work as expected. The equivalent long option --difference does work as expected.

```
$ watch -d ls -l
watch: invalid option -- l
Usage: watch [-dhntv] [--differences[=cumulative]] [--help] [--interval=] [--no-title] [--version]

$ watch --difference ls -l
(works as expected)
```

I apologize in advance if this is not a Brew problem. I tried checking the news archives of the procps project on sourceforge first, but I wasn't able to find any related reports about this issue there. (Admittedly the archives are chock full of spam, but I would have expected reports about this issue to be frequent and recent if they were present at all.) Google searches for the issue are difficult given the generic keywords required (`linux watch difference usage "-d"` ... ?). Figured I would check here first to see if anyone else had the same problem, then work backwards.
