mdwtools.tex: Fix spacing of footnote markers in the document title.

The default document classes, and, separately, the `doc' package,
arrange for `\maketitle' to set footnote markers without taking up
horizontal space.  Apparently, if you have author names with
affiliations in footnotes, then the footnote marker shifts the names
visually off-centre.

We don't have this problem here, so turn that off, and remove the
compensatory `\space' following the marker.
