rev-list: allow -n<n> as shorthand for --max-count=<n>
Both -n<n> and -n <n> are supported. POSIX versions of head(1) and tail(1) allow their line limits to be parsed this way. I find --max-count to be a commonly used option, and also similar in spirit to head/tail, so I decided to make life easier on my worn out (and lazy :) fingers with this patch.
