I think it's very useful to also have a funct that does all of that, but I 
agree that normalize is a bad name for it.

What do you think about having stripTop and stripBottom functions? (Ie, 
Removing all white-space-only lines from the top or bottom of a string. 
assert(stripTop("   \n  \t \n\tA") == "\tA") ) If those are there in 
addition to outdent, then a user could trivially combine them all into one 
util func if they wanted.

In any case, I'll make a pull request for outdent.
