I'm definitely against not having newline conversion.

(O.K., easy for me to say, I'm not implementing it ...)

As long as people use editors that don't behave nicely in the presence
of different line ending conventions (and this will be forever), newline
conversion actually helps maintain the integrity of the repository.

As long as there are compilers that barf on a non-native newline (wich
most Unix compilers do), and people share code between different
flavours of systems ... well, same as above.

As to newline conversion being outside the scope of a version control
system ... strictly speaking, so is support for showing diffs on text
files. you only *need* to be able to get the different versions, you can
diff them yourself ... (ok, ok, never mind.)

Last but not least, this is something other SCM systems provide, and
users will expect it.
