Uhmm... if it wasn't documented, all the more reason to be careful.
# tab-width:4 (or however it's done)
<quadzillion of lines>
<4 spaces>for record in database:
< 8 spaces > process_record
< 1 tab > del database
Now, I completely agree that that is very fragile code (imagine some emacs
loathing colleague removing the tab-width line) but that doesn't mean we
should just break it for the hell of it... We have it, we want to lose it,
we deprecate it. If we rip it out now (which I'd be -0 on) we should replace
it with an *error*, not a warning, since code has a high chance of breaking.
