Change Log's style nitpicking!

[Mathieu Lirzin]

Hi,

A few weeks ago, I noticed that when passing the Guix commit logs to
‘gitlog-to-changelog’, the result is not properly displayed in Emacs.

For example with:

--8<---------------cut here---------------start------------->8---
        gnu: Add python-oslo.log.
        * gnu/packages/openstack.scm (python-oslo.log,
          python2-oslo.log): New variables.
--8<---------------cut here---------------end--------------->8---

Change Log mode requires a parenthese as a first character with only a
tabulation before (no extra space) to fontify the ‘python2-oslo.log’
with the same style as ‘python-oslo.log’. In fact it imposes precisely
what is documented in GNU Standards:

  https://www.gnu.org/prep/standards/standards.html#Style-of-Change-Logs

I will not claim that this is a major issue, but since we try to use GNU
Change Log's format, let's conform to it. ;)

Let me precise that my point is not about personnal preference (I prefer
the current format), but it is about consistency within the GNU project.

What do people think?
