+1!!

I wrote this exact patch myself a few weeks ago, but didn't bother
with tests and hadn't gotten around to sending it in.  Thank you for
doing it right, Eric!

Here's why I want this: I would like to be able to run

  $ hg log --template "{node|short}  {branch}  {desc|firstline}\n"

fairly regularly.  Currently I kludge it with

  $ hg log --template "{node|short}  '{branches}'  {desc|firstline}\n"

where I just know that '' means 'default'.  Blech.  This is very weird
and obscure, and hostile to piping the results to awk or grep or
whatever.
