3) I spent a bit being very puzzled about why C-h v
org-archive-save-context-info yielded the claim that there was no
matching variable. It also didn't show up in the customize
interface. Puzzled, I created a dummy headline to test what would
happen on archiving. After archiving once, the variable exists. Is
there some reason for making the variable dependent upon an
invocation of org-archive-subtree? I doubt it will confound me
again, but there wouldn't have been a problem were the variable
initialized when org-mode is entered rather than upon a first
archiving.
Well, the problem here is that Org is now set up in a modular way, and that
many variables are in subfiles that are only loaded when needed. I am aware
of the problem and would like to fix it, but I do not know a good way
to do so.
If you like you can call `org-require-autoloaded-modules' in .emacs after the
(require 'org-install)
(org-require-autoloaded-modules)
and that will load everything.
