description:
lowdown: update to 0.4.1.  From Charlotte Koch.

Push diff implementation (from libdiff) directly into the code instead of using the external library. From a patch by Anton Lindqvist as suggested on the OpenBSD ports mailing lits. Thank you!

Significantly update the diffing algorithm. First, make some general fixes to the algorithm. Second, improve the "optimisations" phase by adding top-down analysis that matches un-matched, 
non-terminal adjacent children. This helps with text changes in text-only paragraphs. Third, add a SES (shortest edit script) computation for matched adjacent text nodes. Lastly, add the new diff 
function manpages.

Portability: don't use %F for date formatting. This doesn't work with some libc versions. Also some documentation readability improvements.

Strip leading white-space from metadata extracted using -X. Sync with newest oconfigure.

Document the metadata functionality in lowdown(5), thanks to Christina Sophonpanich (thanks!). Also sync with newest oconfigure.

Add a "diff" tool, lowdown-diff(1). This utility uses an algorithm adapted from Detecting Changes in XML Documents to compute the semantic difference between two parse trees. It is fully documented. 
While there, also add more inter-paragraph spacing to -Tms output, producing more elegant documents, and continue fleshing out lowdown(5). Also add some more metadata recognition in -s output for all 
modes (copyright, affiliation, etc.).

Re-wrote escape parser to -Tms and -Tman to respect roff special characters. Have e-mail autolinks respect the mailto: in pdfhref'd output, and have links with mailto: omit the schema in display just 
like in -Thtml. Make block-list-items render properly in -Tms and -Tman. Also introduce lowdown(5), a work-in-progress to document the Markdown formatting accepting by this system. The first were 
noted, and the last contributed in full, by Christina Sophonpanich ? thanks!

Fixed compilation on Linux and Mac OS X by adding memrchr compatibility. Noted by Christina Sophonpanich ? thanks!

Considerable clean-up of -Tms and -Tman, with the aim of much higher PDF output quality: proper nested list support, hyperlinks, PS/PDF TOC, and even some images (PS/EPS only?experimental!). Also, 
after some pointers on the groff mailing list, use the correct invocation for generating PDF output. Fix up footnote printing to use automatic -ms macros and registers, if applicable.

Also added support for the "affiliation" metadata keyword.

Added some CommonMark support, initially just escaped newlines, supported only when the commonmark input flag is specified. Removed the sphd input flag in favour of commonmark. Also fixed raw HTML 
block outputting and setext-style level-two headers.
