If a value is convertible to 'text, then use that conversion.
Otherwise, convert using `write` instead of always using "???".
Also, correct documentation to include convertible values among
the valid forms of content, and document the new conversion rules
there.
I'm not certain that mixing 'grouper and non-'grouper parts at a given

counting more in line with Latex, so that section links are less
likely to have the wrong number label.
add contracts to location-formatting functions,
and make sure those functions convert their inputs to strings,
and fix a documentation bug in `techrpt-location`
These commands work like natbib's citeauthor and citeyear commands,
and facilities making possessive citations. For example:
> Thanks to @(cite-author foo)'s (@(cite-year foo)) paper on stuff...
These identifiers are added with `define-cite` as keywords, and thus
can be omitted with no downside for backwards compatibility.
@(define-cite cite citet generate-bib
#:cite-author cite-author
#:cite-year cite-year)
Also in this commit:
* Add documentation.
* Add tests for autobib
* Bump version and add history.
