No *single* standard.

You forgot the other tab standards. In the US, the default tab stops are 
at 1/2 inch intervals, which is 5 or 6 chars for fixed 10 or 12 pitch 
fonts. Most email is not code from programmers and their bizarre (to a 
non-programmer) and dis-functional choice (sometimes) of 8 spaces.

<\t> would be better than nothing. Let us see what Thunderbird does 
*now*. Maybe complaints prompted a change. Or maybe some clients eat 
tabs upon sending.

     4 spaces
         8 spaces
	tab, which displays as 8 spaces on input
		2 tabs

Regardless of what shows, there is still no configuration option.
