Well, tab spacing issues go back as far as there do word processors. No point in getting your knickers in an twist over it.
At least if the tabs are preserved as tabs and not converted to spaces, everyone can set their own preferences in their editor. Then again, there is search and replace but that works better in one direction than the other. You can search for tab and replace with space easily, but the other way around is not as straight forward.
