[PATCH] control/limit output of git-rev-list 

gitweb.cgi's default view is the log of the last day and git-rev-list
can stop crawling the whole repo if we have all our data to display in the
browser. Also the rss-feed query needs only the last 20 items. This
will speeds up these queries dramatically.

  usage: rev-list [OPTION] commit-id
    --max-count=nr
    --max-age=epoch
    --min-age=epoch
