PATCH: Fix a bug in _git's clone completion

[Frank Terbeck <ft@bewatermyfriend.org>]

There was a backslash missing at a line end, which screwed up things.

Also, I don't understand the completion after 'git clone --bare <tab>'.
It does not give me *any* completions, while I would expect the same
completions as without the --bare option.

If I do 'git clone --bare -<tab>', I only get a small subset of the
remaining options. I don't know what is happening here.

Finally, I do not understand why the end of the _arguments call was
done like this:

[snip]
    ':repository:__git_any_repositories' \-
    '*:directory:_directories' && ret=0-
[snap]

...and not just: '*:repository:__git_any_repositories' && ret 0

If someone can explain, please do ahead. :)
