Subject: mdwtools.tex: Set a running header without footnote markers.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/mdwtools/commitdiff_plain/bc1b2c52955504200818fb858a7e792707a7475a?ds=sidebyside

mdwtools.tex: Set a running header without footnote markers.

The `strayman' document class, in particular, sets a running header with
the document title by default.  But if the title contains footnote
markers then these end up in every (other) page header, with steadily
incrementing numbers, which is rather bad.

The hack here only supports `strayman'.  Most classes don't have
`strayman''s optional running-header argument for `\title', so I can't
use that.
