When columns are set to automatic for git tag and the output is paginated by git, the output is a single column instead of multiple columns.
Standard behaviour in git is to honor auto values when the pager is active, which happens for example with commands like git log showing colors when being paged.
Since ff1e72483 (tag: change default of `pager.tag` to "on", 2017-08-02), the pager has been enabled by default, exposing this problem to more people.
finalize_colopts in column.c only checks whether the output is a TTY to determine if columns should be enabled with columns set to auto. Also check if the pager is active.
