Seems to me 'svn xyz [...] -h [...]' should rather become 'svn help xyz',
dropping all(?) other option args.

I actually never realized -h existed, but to investigate an erratic
command line, I'd find it more convenient to add '-h' than having to
insert 'help' as first arg.

OTOH it's not so good to maintain several ways of reaching the same
outcome. But I guess now that -h is already in the client, we might as
well make it convenient to use.
