git branch --merged and git branch --verbose do not combine

dak@lola:/usr/local/tmp/lilypond$ ../git/git branch --merged --verbose
fatal: malformed object name --verbose
dak@lola:/usr/local/tmp/lilypond$ ../git/git branch --verbose --merged
* (detached from 5b2267a) 1c23f39 Merge branch 'issue4097' into HEAD

So depending on the order of --verbose and --merged, one gets an incomplete list (basically ignoring --merged) or an error message.

Since both behavior and naming of the --verbose option is more or less orthogonal to other listing options, it would make sense to allow it to combine with them.
