When doing svn log -qr HEAD trunk/url, a log message with revision wi…

…ll not

show if the last commit was not in the trunk/ path.

For example, changeset [4045] is for scriptaculous, so the command executed by
rails:freeze:edge:

svn -qr HEAD log http://dev.rubyonrails.org/svn/rails/trunk

Yields the following output:
------------------------------------------------------------------------

Change the command to use --limit 1 instead of HEAD, which will pick up the
last changeset against the trunk path.

Fixes #4356
