I think this used to work correctly before because I have memories of testing this when responding to makefile questions before, where proper tabs are crucial. (That would have been before the switch to CommonMark.)
But at least as of last night, putting a literal tab in a code block in an answer of mine no longer works, and instead produces four spaces.
(My answer initially had ```make but I changed it to ```makefile in accordance with the guidance; but this didn't seem to matter.)
This means the code can no longer be correctly copy/pasted by visitors to the site. Could this please be changed (back, I assume)?
