Subject: Conflict between RCS tag and (e.g.) php description

In some  languages the `$` is used to start a variable name (php, perl).
When having a description like:
```
 <b>$RRDp::error_mode</b>, <b>$RRDp::error</b>
```
this will lead to a message like:
```
warning: found </b> at different nesting level (4) than expected (2)
```
because the part `$RRDp:` is seen as start of a RCS tag and runs till the next `$`.

Though the `::` indicates here a class / namespace separator and in case of `$...:`  directly followed by a `:` this should not be seen as RCS tag.
