CRLF in upstream source code

[Lourisvaldo Figueredo Junior <lourisvaldo@figueredo.tec.br>]

Hi everyone,

I have a doubt. In cases where the upstream uses the MS-DOS pattern CRLF 
("\r\n") to end of line, instead Unix pattern LF ("\n").
In this situation, should the maintainer make a patch converting this files to 
the Unix pattern LF?
Or to Debian is 'acceptable' to build a package from source keeping the MS-DOS 
pattern CRLF?
The question is about the upstream source code, not to the debian directory.

Thank so much.
