Looks good to me, so I've applied both patches to Emacs 28.  Eli had
some questions about the usage of user-error instead of error in the
second patch, but as far as I can tell, using `user-error' is indeed the
right thing here, because the errors in question seem more user
initiated.

I've got two tiny comments about the patch.  First of all, the
whitespace seemed odd:

lisp/ses.el:3462: space before tab in indent.
+         	  (currow (1+ (car (ses-sym-rowcol curcell)))))

So I fixed that up, but I've seen that in other patches -- could you
have a look and see what's causing this mixture of tab and spaces?

The other comment is that it would be nice to have ChangeLog-style
commit messages -- use `C-x 4 a' to format one before sending patches.
Less work when applying the patch.  :-)
