store: exclude `undo.` nodemap's file from `walk`

There are "temporary" local file that we should not be transfered by `walk` user
like local clone and stream clone.

This fix the small issue that the new tests highlighted.

'''browse command output with an external pager (DEPRECATED)

Forcibly enable paging for individual commands that don't typically
request pagination with the attend-<command> option. This setting
takes precedence over ignore options and defaults::

  attend-cat = false
