& (align_selection) does not take the rendered width of tabs into account

[emilyyyylime]

Summary

When using & to trigger align_selection, the editor only aligns based on the amount of characters, without taking into account that some characters may be wider than the others, like tab (0x09).

Reproduction Steps

I tried this:

1. hx
2. wrote

	abcde # this line contains a tab
        abcde # this line contains spaces

(i [tab] [enter/linefeed] [4 spaces (depending on your tab width)] [esc] [A-C] i abcde [esc])
3. typed &

I expected this to happen:
the 2 cursors should have appeared vertically aligned (they probably already were)

Instead, this happened:
the cursor on the line with a tab character has been padded out with n-1 spaces, where n is the width of a tab
