[Swift-devel] Code style

Person A commits some code with a single tab indent.
Person B has their display set to tab = 8 and adds new lines with 8 spaces 
rather than using the existing indentation byte sequence.
Person C has their display set to tab = 4 and adds new lines elsewhere in 
the file with 4 spaces, rather than using the existing indentation byte 
sequence.

Now you have a file with both 8 space tabs and 4 space tabs.

it seems hardest of all to stop people using their own favourite 
indentation sequence rather than the pattern already used. (make tabs and 
spaces have different colours and a bunch of the communally edited code I 
work with looks pretty puke)
