Add option to toggle git log --cc for less touching about gource HOT 6 CLOSED

[deleted comment]

Hi. I'm a bit confused by your example, I'm guessing you left something out by 
accident.

If I use --cc with git log on the Gource repo I see 3 additional changes marked 
with
an MM:

    ::100644 100644 100644 da250cd... bab26a3... 0c51408... MM    src/gource.cpp

    ...

    ::100644 100644 100644 d93d910... 5e688e1... 8011ad3... MM    src/gource.cpp
    ::100644 100644 100644 88850c3... a56fa21... e24c4c5... MM    src/main.cpp


Kind of makes me wonder if the behavior has been changed between git log 
versions.

Hmm.  I'm using Git v1.6.5, but I think we're seeing the same things.  In my 
diff of
the two methods on the Gource repo, I see:

(There's more to the diff, but that's the relevant part.)

In both cases, the git log now has an extra line break between the two different
users.  This causes Gource to ignore the first user (who only merged the 
codelines
but didn't actually touch the files) and only show the second user as touching 
the
file (with the beam).

It's not so pronounced in the Gource repo, but my students are using the repo 8 
hours
per day or more, committing roughly every 30 minutes.  This leads to dozens of 
merges
per day, and the changes are far more obvious.  When the merges are counted, it 
looks
like students are all over the place, writing to each other's files.

I don't know that I want to post a git log to a public forum such as this, but 
I'd be
happy to email (a moderately anonymized) one to you so that you could see the 
difference.

I thought some more about this and realised I could fix this in the commit 
parser
rather than change the log command.

I've made the Git log parser use the LAST username and timestamp before the 
list of
files rather than the first.

Could you have a go with the updated archive and see if it looks right now?

Works like a champ, as near as I can tell.  Thanks!
