Hmm... yes, I guess I could do it, but determining the appropriate number of spaces seems to get quite complicated.
Vim seems to remove a single space if, between tab and space, space was the last key pressed in the current insert mode.
I would have to map space to set a variable (l:space_last_pressed or something) to true, and also map Esc and Tab to set it to false, then use the variable's value to know how many spaces to make up for.
As I said, I guess I could do it, but isn't there another way? :/
