tools/dev/mk_manifest_and_skip.pl should remove file from the MANIFEST
that are scheduled to be svn deleted.
This problem should be corrected with revisions applied to trunk today
in r19893 (which applied to RT 43847 as well.
Both Coke and I have verified in practice that this will solve the 'svn
delete' issue. But I'm going to leave the ticket open for a while in
the hope that I can write a formal test for it.
These tests will generate a failure if either MANIFEST or MANIFEST.SKIP
is in a state where it needs updating. So it doesn't hurt to run them
periodically, even though they are not a part of 'make test'.
