If parent J is an ancestor of parent I, then parent J should be
discarded, not I.
Note that J is an ancestor of I if and only if rev-list I..J is emtpy,
which is what we are testing here.

When svn:mergeinfo contains two new parents in a specific order and
one is ancestor of the other, it is possible that git-svn discards the
wrong one. The first test case ("commit made to merged branch is
reachable from the merge") proves this.
The second test case ("merging two branches in one commit is detected
correctly") is just for completeness, since there was no test for
merging two (feature) branches to trunk in one commit.

Add a partial branch (e.g., a branch from a project subdirectory) to the
git-svn mergeinfo test repository.
Add a tag and a branch from that tag to the git-svn mergeinfo test repository.
Update the test script to expect a known failure in git-svn exposed by these
additions where merge info for partial branches is not preserved.

The old function was incorrect; in some instances it marks a cherry picked
range as a merged branch (because of an incorrect assumption that
'rev-list COMMIT --not RANGE' would work). This is replaced with a
function which should detect them correctly, memoized to limit the expense
of dealing with branches with many cherry picks to one 'merge-base' call
per merge, per branch which used cherry picking.

SVN's list of commit ranges in mergeinfo tickets is inclusive, whereas
git commit ranges are exclusive on the left hand side. Also, the end
points of the commit ranges may not exist; they simply delineate
ranges of commits which may or may not exist. Fix these two mistakes.

As shown, git-svn has some problems; not all svn merges are correctly
detected, and cherry picks may incorrectly be detected as real merges.
These test cases will be marked as _success once the relevant fixes are in.

When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from. When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.
In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.

git-svn: add (failing) test for SVN 1.5+ merge with intervening commit
This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
properties. The problematic case is when there is some commit on an
unrelated branch after the last commit on the merged-from branch.
When SVN records the mergeinfo property, it records the latest
revision in the whole repository, which, in the problematic case, is
not on the branch it is merging from.
To trigger the git-svn bug, we modify t9151 to include two SVN merges,
the second of which has an intervening commit. The SVN dump was
generated using SVN 1.6.6 (on Debian squeeze amd64).

This feature is long overdue; convert SVN's merge representation to git's
as revisions are imported. This works by converting the list of revisions
in each line of the svn:mergeinfo into git revision ranges, and then
checking the latest of each of these revision ranges for A) being new and
B) now being completely merged.
