<!-- TODO:
- in details of a change, list all branches it applies to
- create separate lists for all changes between one branch and the next
- clearly mark incompatible bits in details of a change, besides text contents
- warn about any changes made after a certain date which incl. additions but
have no associated API version
- ability to display authors in pretty format
- kill $api-list and select from /apichanges/apidefs/apidef instead to get an
API list (but the hack is still needed for index by affected class)
- whenever <hN> tags are used as part of a changelist template, the proper
header level should be computed based on the surrounding context

Tricky. We list all of the changes as usual, sorted by API and date.
We have already computed what all of the API names are (incl. duplicates)
in order and have this indexed by position in the list. To tell if it
is necessary to start a new group we calculate whether the API of this
change is different from that of the preceding one (and use the same trick
to tell if the bullet needs to be closed). XSLT does not seem to have facilities
to manipulate doc fragments sanely (i.e. use of for-each or array indexing) so
we have to keep the info in a string and use string functions to do it, alas.
