Tab key in INSERT mode tends to jump around in the document instead of indent... Planned behavior, or bug?
Not planned and I don't remember any <TAB> specific code. Odd.
Found the problem... Turns out it's being caused by the supertab plugin (acts the same way in HTML files too).
Sorry for the mis-filed bug. :-)
No worries, thanks for adding information on the root cause. It may help someone later.
