Yes, I know the information is available somewhere, but I'm going to stress
the point that it's impossible to properly extract it.
If you do a single merge that spans 20 revisions, there is basically no
level at which Subversion knows which revision each line of change comes
from, especially since the user is free of fixing conflicts (which might
mean renaming couple things, moving things around across files and so on)
before the commit. After the commit happened, a property simply pointing to
the list of revisions from which the merge was done might be enough to
reconstruct information for "svn log", but surely not for "svn blame" and
maybe not even for "svn log -v". Even if you exclude the case of conflicts
manually fixed by the user, only back-guessing (for the purpose of svn
blame) the normal context heuristic done when a patch is applied looks
pretty hard to me.
Unless I'm seriously missing something, which is very well possible since
I'm no SVN guru :)
