Autocomplete of keywords breaks the code

[svivian]

Type {% b and a dropdown to autocomplete 'block' will show up. But when I press tab, instead of autocompleting it inserts the entire block inside what I already typed, so I end up with

{% {% block name %}{% endblock %}}

In other words, it only replaced the b and not the existing parts of the tag.

Doesn't happen with HTML auto complete - when you type <div then tab, it completes the div tag and doesn't add extra <
