Which plugin is removing blank spaces at the end of lines when writing?

[capn-freako]

I'd like to disable the automatic removal of blank space at the ends of lines in my Haskell code, so I can better control the resultant formatting of the Haddock generated documentation (by forcing line breaks, using two blank spaces at the end of a line).

Does anyone know which plugin is responsible for removing blank space at the end of lines when writing out the file?

It is from a utility function defined in .vimrc:

haskell-vim-now/.vimrc

Lines 421 to 426 in f55a720

	" Utility function to delete trailing white space
	func! DeleteTrailingWS()
	exe "normal mz"
	%s/\s\+$//ge
	exe "normal `z"
	endfunc
