This has been the situation since before the first public release of MacHg. However some people have commented that they would like less of a delay in looking at the full details when scrolling through the list and looking at a particular item.

Thus I would like a way to do this from within a single log command.

Well. The "proper" way might be to add a multiline filter in templatefilters.py
This way you would write {file_mods|multiline} and it could work for
{file_adds|multiline} and so on.

Perhaps it's not perfect:
* until now, most filters could apply to both item lists, and single
items; and multiline is cleary list-oriented
* Templating code might or might not get broken if you start using
multiline items (in glog maybe)

But it seems like the reasonable (tm) approach if you _really_ need to
extend templates to do this. Otherwise you'll have to add one
*_multiline keyword for all applicable keyword, and it's uglier.
