Answering my own question...
The IDs of all the assigned categories are stored in an array called
aSelected. This array is updated as boxes are checked and unchecked.
If you want to grab the values before submitting the form you can do
something like this:
**************************
Before form
***************************
<script>
function updateCatIDs() {
obj = document.getElementById('selectedCats');
for (i=0;i<aSelected.length;i++) {
obj.setAttribute("value",aSelected.join(","));
}
}
</script>
****************************
Start of form
****************************
<form action="#cgi.script_name#?#cgi.query_string#" method="post"
name="editform" onsubmit="updateCatIDs();">
<input type="hidden" name="bRelatedPagesSubmitted" value="1"/>
<input type="hidden" name="selectedCats" value="" id="selectedCats"/>
***********************************************
Hopefully we can get that fixed in the core sometime soon because it's
a bit of a pain to have to do it on every page that uses the category
assignment form.
