[TxMt] find/replace in column selection

Hi Folks,

I've just started using TextMate and I'm very very impressed. I've noticed the following behaviour and I wonder if anybody could let me know if this is a "feature" or a bug.

I make a column selection and I replace "foo" with "foobar". This increases the width of the column selection. Here is the problem -- any continuous text that passed through the column will now be broken and expanded with spaces. This is not what I would expect and it will seriously limit my use of find/replace in column selections.

Is this a bug? Or is it an operator error?

Thanks, Leo
