textproc/ruby-kramdown-rfc2629: update to 1.3.37

1.3.37

Contributors can be annotated with text that will be added to the
Contributors section after their contact information.
The text is entered in the "contribution" entry of the contact
information for a contributor.
It is markdown and can contain paragraph breaks and other markup, as
shown below (with some author information as context, which is not
shown in the rendering).
Note that YAML has the "|" syntax that is strongly recommended for
entering markdown text into YAML entries.

1.3.36

new: kramdown-rfc-cache-i-d-bibxml

1.3.35

revert to <artwork> if "artwork-align" is set …

Bizarrely, RFCXMLv3 does not allow an "align" attribute on
<sourcecode>, while it does on <artwork>.  This, together with the
automatic assignment of <sourcecode> to appropriately classed code
blocks added in 1.3.34, creates a backwards compatibility problem.

This is now worked around by reverting to <artwork> for any code
blocks that do have "artwork-align"/"sourcecode-align" inline
attributes, regardless of type.  So if you want your source code to
turn up as <sourcecode>, do not center/right-adjust any more.

1.3.34

map most codeblock classes to <sourcecode> instead of <artwork>
RFCXMLv3 introduces a second element for verbatim text beyond
<artwork>, the <sourcecode> element.
So kramdown-rfc needs to decide whether a codeblock turns into
<sourcecode> or into <artwork>.

1.3.34 now maps all code blocks with a language given to sourcecode,
except if the language is one of (ascii-art binary-art call-flow
hex-dump svg).
(This exception list was appropriated from RFC 7991; the current
xml2rfc documentation doesn't mention call-flow or hex-dump.)

KRAMDOWN_NO_TARGETS: let xml2rfc fill in the targets for RFC and I-D

1.3.32

o xperimental persistent connections to use this:

	* gem install net-http-persistent
	   (this is not an enforced dependency of the gem!)
	* Set environment variable KRAMDOWN_PERSISTENT to any value

  KRAMDOWN_PERSISTENT= kdrfc -3chi foo.md

o Mark can_anchor as unused in the stand_alone: true code.
