Well, first check that

Aha, thanks. That helped me determine that my Vim silently ignores me
when I try to set relative directories for undodir.
:set undodir=. works fine, but no undo file is created when I :set
undodir=./undodir
This seems to be a different behavior than that of backupdir, even
though :help undodir says "See |'backupdir'| for details of the
format." Is this expected/documented/fixable?
Hm, setting 'undodir' to a relative directory works for me. I can't
reproduce this. However there is a bug when using rundo with those
files.
When using a separate 'undodir' directory to store the undofiles, Vim
uses the complete path of the file as filename, replacing the path
separators ('/') by '%'. So far this works as documented by :h
'undodir'.
Now when using :rundo with a filename, that contains the complete path
and using '%' as directory separators, those '%' will be replaced by
the current file name (as documented by :h filename-modifiers) and
surprise surprise Vim won't be able to read the undofile.
So this is just plain wrong in this case. So here is a patch, that
fixes that. This applies only to :rundo and I am not sure, whether
this should also apply to :wundo (I tend not to apply it there) but
this should be kept in mind.
Bram, please check and apply.
In most places where you can use a file name % is expanded. And it's
also useful, especially in the form "%:h" to get the directory.
I don't understand. Using '%' as path separators contradicts the usage
your pointing out. How am I supposed to :rundo an undofile, that
contains the '%'-separator?
The path separator is % in 'undodir' but / in the operand of :rundo (see
the examples under ":help :rundo").

Burn's Hog Weighing Method:
(1) Get a perfectly symmetrical plank and balance it across a
sawhorse.
(2) Put the hog on one end of the plank.
(3) Pile rocks on the other end until the plank is again
perfectly balanced.
(4) Carefully guess the weight of the rocks.
