[Doxygen-develop] Some meta tags are not properly closed.

Hi,

When I run doxygen built from git head on some of my source the resulting html has meta tags that are not properly closed (and fail to pass the w3c validator as a result). The following is a sample of the html output (from html/search/all_0.html):

<html><head><title></title>
<meta http-equiv="Content-Type" content="text/xhtml;charset=UTF-8"/>
<meta name="generator" content="Doxygen 1.8.6">

Note that the second meta tag is not properly closed (and as the doctype of this file is XHTML it needs to be).

This trivial patch resolves this issue:

diff --git a/src/searchindex.cpp b/src/searchindex.cpp
index 7aa8216..a550eb1 100644

Hope this is useful
