Do we have a timeframe for 2.3/2.4? If these debugging messages might help
me fix register problems then it could be worth adding them in 2.2, because
then users will be better able to help me. That could help get some register
bugs fixed in trunk before 2.3/2.4. Otherwise register bugs may just
continue to sit around. I'm definitely not saying to backport the actual
fixes for 2.2, but at least backporting the debugging messages may help keep
I'm just sort of wary of getting into the situation where there's a new
stable release and fixes will be quarantined in trunk again. So I'd like to
get some register fixes done before the next stable release goes out, and
these debugging messages may help.

Agreed, however this particular changeset (r17841) doesn't change any
functionality - it is all edits to comments except in two spots where a
function declaration in the .h file had a different parameter name from in
the .c file. Simple typos -- I just made them match. Anyway that changeset
is just for documentation, so no problem, no need to backport it. There will
be another doxygen changeset committed soon. I won't mark that one for

I think the debugging code is a very safe change. The code doesn't even run
unless the --log option is set. If you look at r17837 and r17838, all you'll
see are new ENTER(), DEBUG() and LEAVE() statements. For r17839, if the
variable name change worries you then don't backport it, that's fine.
There's only one new debugging message added in r17839 anyway.
