[O] Bug: Group tag filters repeated per org-file [9.1.13 (release_9.1.13-751-g9dcc52 @ c:/D-Drive/bin/org-mode/lisp/)]

[Bernt Hansen]

Hi,

This bug is mainly a visual annoyance when filtering by tag in the
agenda.  It is low priority to fix but I thought I should report it
anyway.

Thanks for all your fabulous work on org-mode!

Regards,
Bernt

*Keys To Reproduce*

1) Add test.org to org-agenda-files 
   C-c [ 

2) open agenda
   C-c a a

3) Filter by tag
   /
   shows 'Filter by tag [123whPfdDQMEc? '
   This is correct.

4) quit filter
   C-g
   
5) Switch back to test.org
   C-x o

6) Add a second org file to org-agenda-files
   C-x C-w test2.org RET
   C-c [

7) Add test.org to org-agenda-files 
   C-c [ 

8) open agenda
   C-c a a

9) Filter by tag
   /
   shows 'Filter by tag [123123whPfdDQMEc? '

   There is an extra '123' filter choice. One per org-agenda-files entry.

   On my setup I have 8 files in my org-agenda-files and '123' is
   repeated 8 times before the other filter options.

   shows 'Filter by tag [123123123123123123123123whPfdDQMEc? '
