Commits B, C, and D are not included in the git log -S output even
though with gitk you can see that 'org-publish-validate-link' is in the
patch.

It is not sufficient for it to be in the patch, it has to be added or 
deleted in whole.  So for example if you had a line

	org-publish-validate-link Hello

and you changed it to

	org-publish-validate-link World

git log -SWorld will find the commit, but git log 
-Sorg-publish-validate-link will not.

It seems nobody has looked at the actual commits, but Dscho got it 80%
right.

There seems to be a misconception on what -S<foo> does.  It does *NOT*
grep for string <foo> in the patch text.  It counts number of <foo> in
preimage and postimage and decides that the commit is worth showing iff
they differ.

If you look at, for example (B):

    http://repo.or.cz/w/org-mode.git?a=commitdiff;h=837c81ce51

You can see that in org-publish.el, org-publish-validate-link appears once
as removed and once as added, so the total number of the appearance of the
symbol in preimage and postimage are the same.

Now I get it :)

Thanks both of you!
