Using bold( ) with no text selected does not create <strong>

[lucthev]

Previously, with the following html:

<p>Stuff|</p>

executing the bold command would lead to the following:

<p>Stuff<strong>|</strong></p>

Now, however, nothing happens; the html remains the same. This seems to have been introduced by 6461294 (semantic bold/italic). This issue also applies to the italic command.
