The times that whitespace indentation has bitten me, it was still not 
difficult to fix -- I just had to look and see which line(s) 
should/should not be where they were.

I fix the block, then move it as I need to.

Not so.  If the braces do not match /intent/ (which is the problem I 
care most about) then it cannot be fixed by machine.

I can see where a messed-up mail server could cause hours of grief.  Not 
having experienced that, but only cases where I, myself, accidently 
changed indentation when I should have, it's not been a big deal to fix; 
I'm willing to live with not having the machine reformat my source code 
from incorrect to correct.

Your choice, obviously -- seems a shame to me, though, to give up on 
Python because of one or two ouchy areas on c.l.py.  By and large it's a 
very helpful and courteous community.
