The patch to org-eldoc applied in b2b587387 still throws an error:
eldoc error: (void-function nil)
I was unable to step through this because (I think) eldoc causes
the debugger to close as soon as input is received. The error
occurs when `eldoc--invoke-strategy` attempts to funcall
eldoc-documentation-default.
The attached patch works for me, but I do not know if it is the
correct solution.
