The idea would be to provide scripts for each step that people think
should be easier/automated. Like running the provided testcase before
and after applying the corresponding patch. Or making sure to build
before running tests for a patch that touches C code.

Who's handling those bugs? Is any of them avoidable/easier to
catch/easier to workaround with a script that checks for, e.g.,
svnmerge version, svnmerge correct usage and completeness of the
merge? I think this proposal could help reproducing those issues and
fixing/mitigating them until a better solution is available.

Maybe something could be improved in svnmerge, as Martin suggests. Or
merging could be made a bit easier, so people would backport their
commits themselves more often and the laundry list merges could be a
little smaller.

We have discussed this off-list and I have no answer regarding SVN limitations.

If a svnmerge-on-top-of-hg or svnmerge-on-top-of-bzr script can be
used to merge SVN branches with the exact same results of the real
svnmerge, only faster and prettier, maybe it should be considered for
GSoC too.

If/when the main Python repository moves to a DVCS, scripts that allow
people to perform the same steps they currently perform to achieve the
same results might help the transition.

I won't mention the bzr-on-top-of-git part :)
