Can Git really track the movement of a single function from 1 file to another? If so, how?

Question

Several times, I have come across the statement that, if you move a single function from one file to another file, Git can track it. For example, this entry says, \"Linus sa

A bit of this functionality is in git gui blame (+ filename). It shows an annotation of the lines of a file, each indicating when it was created and when last changed. For code movement across a file, it shows the commit of the original file as a creation, and the commit where it was added to the current file as last change. Try it.

What I really would want is to give git log as some argument a line number range additionally to a file path, and then it would show the history of this code block. There is no such option, if the documentation is right. Yes, from Linus' statement I too would think such a command should be readily available.
