I agree, this is important.

I often need to paste some data to process it by script. The script is oriented on tabs (\t) as data delimiters. So if I just paste data into Sublime Text 2 I got data separated by 1 or 2 spaces ("indent to tab" option) so this is not only inacceptible for my scipt it is also not modifiable because I don't know where the space is a space or just a short tab.
