Do not enforce two newlines after the options

[Seldaek]

It makes things ugly when the last thing you print is the usage() output, resulting in something like:

$ rust run foo.rs -h
Lala

Options:
    -h --help           display this help and exit
    -V --version        output version information and exit

$ prompt

I guess beauty is in the eye of the beholder since presumably we added those newlines specifically to separate the usage output from the succeeding prompt. To be clear this change will result in output like the following?

$ rust run foo.rs -h
Lala

Options:
    -h --help           display this help and exit
    -V --version        output version information and exit
$ prompt

What is the precedent here and are there any accepted standards?

[brson]

Either way, it seems like this should be encoded in the getopts usage string and not open-coded at every call site.

Ok, I tried a few different binary's --help option and none included the extra newline...

Thanks @brson, indeed it's not a common practice as far as I can see, and I prefer to leave the choice to the caller (of course one could strip the last \n but that's less obvious than adding one).
