digging whole history of the file

How can I do (script or svn command) two following things:
    1) for given file x, print series of diffs -rN-1:N for *all* revisions
of the file (fopr every revision that 'svn log x' reports, that is)
    2) for given file x and range of lines M:N in this file, print all
revisions that touched on this region of lines (and optionally,
diffs for that revision for that region only)

For (1), I wonder if there is faster way than parsing svn log x +
bunch of 'svn diff'. This can be really slow.

Thanks
