Subject: impl TextFragmentOneLine for CentredInfoLine.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=9d3765699f4531c90046122e3c943ab77d75709c;p=mastodonochrome.git

impl TextFragmentOneLine for CentredInfoLine.

This always draws exactly one line, and I'm about to want to use it in
a context that expects that and doesn't want to worry about unpacking
a returned vector.
