Subject: strayman.dtx (\@makecaption): Reset rather than unbox wide captions.
X-Git-Url: https://git.distorted.org.uk/~mdw/strayman/commitdiff_plain/refs/heads/mdw/tangle

If we unbox, and TeX decides to break at an existing hyphen, then the
ligature machinery misfires and we get an en-dash at the break.
