Re: Lua-Filter, Span-text to metadata-text: How to get rid of linebreaks in metadata

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

If you don't want any line wrapping behavior, just use
--wrap=none on the command line.

Alternatively, --wrap=preserve will preserve newlines
in your source file.

Does that help or have I misunderstood the problem?
