Dropped off a code snippet and it is wrong when saved

Use
[ code ]
Whatever code you want to post
[ / code ]
With no spaces.
But first, click on "source" on the top left side of the editor.

The editor is kind of a colossal POS for editing posts and what not. 

Like tommy said, I do it manually using the source and the code /code examples Tommy said.

The indentations will stay, but only on first posting, if you edit it, they go away.  Also, if you edit it, everything goes to hell.  So, I try my best to get it right the first time, so I dont suffer the editor.  But it rarely goes as planned
