wow, setting db.max.outlinks.per.page immediately fixed my problem. It looks
like I totally mis-diagnosed things.
May I pose two questions:
1) how did you view all the outlinks?
bin/nutch plugin parse-html org.apache.nutch.parse.html.HtmlParser <local_file>
2) how severe is NUTCH-119 - does it occur on a lot of sites?
AFAIK, HtmlParser doesn't extract urls with regexps. Nutch uses a
regexp to extract outlinks from files that have no markup information
(such as plain text). See OutlinkExtractor.java.

Both this one and the other site you were mentioning (sf911truth) have
more than 100 outlinks. Nutch, by default, only stores 100 outlinks
per page (db.max.outlinks.per.page). Link about.html happens to be
105th link or so, so nutch doesn't store it. All you have to do is
either increase db.max.outlinks.per.page or set it to -1 (which
means, store all outlinks).
