I tend to insert something like
if darcs w -l 2&>-
then printf " (edited)"
fi
to denote that. Here's a rst version I've used. Note that it assumes
patches are chronologically ordered, which is emphatically NOT
guaranteed in a real repository.
$(addsuffix .pdf,$(DOCUMENTS)): %.pdf: %.txt %.meta
rst2pdf $<
$(addsuffix .html,$(DOCUMENTS)): %.html: %.txt %.meta
rst2html $< $@
$(addsuffix .meta,$(DOCUMENTS)): %.meta: %.txt
# Date of last patch to touch any direct dependency
> $@ printf '.. |date| replace:: '
darcs changes --xml --max=1 $^ | \
>>$@ xmlstarlet sel -T -t -m /changelog/patch[1] -v @local_date -n
# Number of patches that touch any direct dependency.

darcs changes --count $^ | \

# Sorted list of authors of those patches. Ignores .authorspellings.
>>$@ printf '.. |authors| replace:: '
darcs changes --xml $^ | \
xmlstarlet sel -T -t -m /changelog/patch -v @author -n | \
sed 's/ *<.*>//' | sort -u | \

I then have the foo.txt file ".. include: foo.meta".
In principle, multi-document sources should DTRT if you add something
like this (untested):
foo.meta: bar.txt baz.txt
Or if your repo only contains one document, you can simply omit the $^s
and generate date/author list/versions for the entire repo.
It'd also be a good idea to include the start of the patch hash, e.g.
darcs cha --max 1 --xml $^ |
xmlstarlet sel -T -t -m /changelog/patch -v @hash |
cut -c 22-27
