Half-width indentation for "where" keyword

I wrote a patch attached to make offsets around `where' configurable.

It introduces 2 new variables, haskell-indentation-where-pre-offset and
haskell-indentation-where-post-offset. Both are set to 2 as default.

They act as follows;
myFun = do
<w>print "hi"
<w>print name
<w1><w2>name = "Mini Me"
 w1 = haskell-indentation-where-pre-offset
 w2 = haskell-indentation-where-post-offset

Could you confirm the patch and apply it to the main repo if it is OK?

Thanks in advance,

# Attached the patch again since my previous mail was not delivered to
the list due to haskell.org down...
