Subject: Simple nospam email address

When having a simple nospam email address coded like:
```
/** \file
 * Big Unknown <big at none dot com>
 */
```
this results in the warning:
```
aa.c:2: warning: Unsupported xml/html tag <big> found
```
and in the HTML output it looks like:
```
Big Unknown <big at none dot com>
```
instead of:
```
Big Unknown <big at none dot com>
```

(Found in a couple of open source projects).
