The question wasn't about programming, it was about Git usage. Technically, it's SU material, but version control applications are traditionally an exception that lives on SO rather than SU. This exception makes some sense inasmuch as version control is rarely used by non-programmers.
This question was migrated by 5 community votes. I don't think they represent anything like a community consensus; I don't recall any discussion on Meta.SO that concluded in a change of policy for version control programs¹.
Since there has been no new activity on the SU side, it would be a simple matter to close the question on SU (which would reject the migration) and reopen in on SO. I'll contact mods to see about this.
¹ Unlike questions about text editors in a non-programming-related usage, where the case for keeping questions on SO is much weaker and has significant opposition on MSO.
