To see how the prettified looks like, the easiest way is to have
a look at any D source code file on the SenseLogic github account
All of them have had their spacings, indentations and alignments
automatically standardized by Prettify.
Basically, it's just Allman style code with leading operators in
hierarchical expressions and four spaces per level of
indentation, so nothing fancy...
Of course, the code style and readability are also a matter of
taste, so it's up to you to decide if you think that the code has
been prettified or "uglified" ;)
