Okay, I must be going nuts. I could *swear* that when editing source, when I backspaced to remove a tab the entire tabstop got removed. All eight character-widths, or whatever my tab size is set to. This happened even if I had soft tabs enabled; backspacing would chew up spaces back to the previous tabstop.
But that's not happening now. Now, when I backspace over a tab, the cursor moves one character and the tab is replaced by (tab size - 1) spaces.
I could also *swear* that up until recently the cursor keys would jump an entire tabstop at a time (if moving over a tab), and that you couldn't cursor into the "dead" space after the end of the line. But now, the cursor keys always move exactly one character width, whether in a tab or past the EOL.
So, did something suddenly change? I'm using the bleeding edge updates, and regularly updating the bundles by svn, so I can see a change slipping past me. Or maybe I toggled some unknown preference value by mistake?
Or is this the way it's always been and I'm just crazy?
