Please checkout the ruby_1_8_7 branch over again if you have one.
Sorry.

Let me look back on this accident.

First, I hit the tag for the final release.

    svn cp branches/ruby_1_8_7 tags/v1_8_7
    svn ci tags/v1_8_7

The commit itself succeeded, but it seems updating the copied
directory's path information somehow failed, so I guess tags/v1_8_7
was recognizing itself as branches/ruby_1_8_7 at this moment.

Then, I found that some unwanted local modifications were included in
the copy which got committed, so I tried to delete tags/v1_8_7 to do
it all over again.

    svn rm tags/v1_8_7
    svn ci tags/v1_8_7

And KA-BOOM!  The commit removed branches/ruby_1_8_7.

Lesson learned: Always do a big commit from a freshly checked out
working directory.
