[GSoC 2010] The 1st week

Hi,

   This is the first week of gsoc 2010 coding phrase, and it is a good
time to summary the previous work and make a plan for the following
two weeks.

What's done:
1. Get familiar with Git code base and have read the code of 'git
blame', revision walk, 'git log'.
2. Try to make some patches for git:
    1. * by/blame-doc-m-c (2010-05-06) 1 commit, in 'next'
    2. * by/log-follow (2010-05-10) 4 commits, in 'next'
    3. the '--graph improvement', in discuss and I think ready for inclusion.
3. Start to write some code for the line level browser feature. And it
is in the 'playaround' branch in http://repo.or.cz/w/line.git . Now,
the code can parse multiple line ranges for multiple files in only one
revision.

What's following next 2 weeks: In next 2 weeks, I will try to make up a version of line level browser that supports code modification trace and this version will print all the diff hunks that touch the interesting lines.

Regards! Bo
