Use 'trimmed' for blocktrans in multi-line strings
blocktrans trimmed option removes newlines from contents of blocktrans
and replaces any whitespace at the beginning and end of a line into
a single space. This makes translator life easier.
It was inspired by a previous patch:
Closes-Bug:
{% block modal-body-right %}
<h3>{% trans "Description:" %}</h3>
- <p>{% blocktrans %} You can create a port for the network.
+ <p>{% blocktrans trimmed %} You can create a port for the network.
If you specify device ID to be attached, the device specified will
be attached to the port created.
{% endblocktrans %}
