Thanks Johathan for your quick and competent reply (as always :-) !

Well, I'll rather wait for your bugfix in the next release, since this 
would involve patching the \@makefntext macro in all standard LaTeX 
classes, as well as memoir, koma-script, etc...

Yes, in standard LaTeX classes the footnote macro contains
\hbox to 1.8em{\hss\@makefnmark}.
The footnote macros in memoir.cls are more complex but the bug has 
basically the same effect. With the koma-script classes, though, the 
effect is as in Plain TeX.

Thanks a lot
