[BUG] (org-agenda-files) after restrict agenda to a file [9.5.2 (9.5.2-gfbff08 @ /home/ignacio/.emacs.d/elpa/org-9.5.2/)]

[Ignacio Casso]

Hello,

After restricting the agenda to a file for a single agenda command, with
'C-c a < a', and exiting the agenda with 'x', (org-agenda-files) still
returns that file instead of the original list of agenda files. This can
be easily solved using the UNRESTRICTED optional argument in
`org-agenda-files', but I wonder if this behavior is correct.

The docstring of `org-agenda-files' says

  "Optional UNRESTRICTED means return the full list even if a
  restriction is currently in place."

But as I understand it, the restriction is no longer in place, since it
was only for the duration of the agenda command, as the Org Mode Manual
says:

  "If you would like to focus the agenda temporarily on a file not in
  this list, or on just one file in the list, or even on only a subtree
  in a file, then this can be done in different ways.  For a single
  agenda command, you may press ‘<’ once or several times in the
  dispatcher. To restrict the agenda scope for an extended period ..."
  *note

This is probably a minor issue, but since it was the cause of a bug in
my config that took me a while to debug, I'm reporting it in case you
think that something should be done about it. In case you are curious
about my use case, I was just doing something like

  (eval-after-load 'a-package
    '(setq org-agenda-files (append (org-agenda-files) (...)))


Regards,

Ignacio
