viewvcs: HTML fixes for commits

The "patch is too large to show" text is now broken by an <hr>
to prevent it from being confused as part of a commit message
(or having somebody intentionally insert that text in a commit
message to confuse readers).  A missing </pre> is also necessary
before the <hr> tag for the related commit search form.
