But a tab isn't 4 spaces.

If someone wrote some code with tab = 4, and committed it, and someone 
else wrote code with tab = 8, maybe even in the same file, there is no 
consistent value to use.

The only thing you can consistently do is copy the byte sequence that was 
used for the block you're adding to. (and even that only works if the 
indentation in that block is already self-consistent...)

Or ban tabs and reformat them away and dock 1 beer point from each person 
who committed the tabs in the first place...
