Email address is not displayed in history

[HirokiGotoh]

Describe the bug
I noticed that email address of Author is not displayed in history.
You can see it on official demo page.

e.g.) http://demo.opengrok.org/history/Lucene/.hgignore

I checked the HTML code, and I found the cause.

<td> Michaa Mccdd <michaa Mccdd@apache.org></td>

I think that correct code is below.

<td> Michaa Mccdd &lt;michaa Mccdd@apache.org&gt;</td>

Workaround
If we use "--userPage" option, an email address can be displayed
e.g.) opengrok-indexer .... --userPage "#" ....

Best regards,
Hiro
