Fortunately the use of resource forks has been strongly discouraged
by Apple for years and years now and you'll find them less and less.

True, but this issue is not limited to Mac OS X, and a Subversion

That shouldn't depend on the OS; it should depend on the filesystem.
On a case-sensitive file system, those are different files. On a case-
insensitive file system, they're the same. True, most UNIX operating
systems default to case-sensitive file systems while Windows and Mac
OS X default to case-insensitive ones.

Yes, a Subversion repository is always case-sensitive.

In Mac OS X the suggested line ending style is LF. CR was used on Mac
OS 9 and earlier and may still be encountered in some old files or
with some programs which predate Mac OS X. Certainly there are
programs that can deal with all kinds of line endings, on any platform.

And vice-versa, I'm sure. :)
