[O] Bug: missing `save-excursion' in `org-fast-tag-selection' [9.2.3 (9.2.3-9-g0803e2-elpa @ /home/il/.emacs.d/elpa/org-20190422/)]

[Ingo Lohmar]

Hi all, 

I tried to use `org-agenda-set-tags'.  The source buffer, where the
change should be applied is visible at the same time as the agenda is.
Also, fast tag selection with a single key is enabled.

Under these circumstances, the tag text is appended to the line (not
even necessarily a heading!) where point is in the source buffer visible
parallel to the agenda, instead of the correct heading that I acted
upon.

I tracked this done to a missing `save-excursion' wrapped around the
`save-window-excursion' in `org-fast-tag-selection' (org.el line 14567
in my version).  This would be analogous to what is done in
`org-fast-todo-selection' and fixes my issue.

Thanks!
