[O] Bug: org-agenda-tags-column does not work anymore [9.1.12 (release_9.1.12-677-g4c13d0 @ /Users/xcy/src/org-mode/lisp/)]

[Xu Chunyang]

Hi,

I'm using latest Org mode built from latest git repository, the HEAD
is 4c13d0a1a870a450627ce1d8449a3b7204202250. I notice tags are no longer
aligned in *Org Agenda*.

It seems the issue is introduced by

    e87ebca2a755620a13a49cc748ba987b17d2d64d Use `org-tag-line-re'

and the following patch fixes it for me
