As well as slightly different images for the vote counts on question the SO questions pages, the code button in the question editing doesn't seem to be unindenting like it used to do.
Is it just me, or was there a conscious decision to stop unindenting, or was there a mistake of some sort in a recent update? (I spotted the problem with 'rev 2012.12.15.619'.)
I was trying to re-indent a question where the C code was about 4 tabstops too far over. I did what I'd normally do: selected the whole of the code and hit the {} button above the edit. A few lines shifted left; most didn't. In the recent past, the whole lot would have moved left. The code in question (I can't understand what is wrong the destructers — the grammar and spelling also need fixing) was indented with a mix of tabs and blanks.
