git-svn: Eliminate temp file usage in libsvn_get_file()
This means we'll have a loose object when we encounter a symlink but that's not the common case. We also don't have to worry about svn:eol-style when using the SVN libraries, either. So remove the code to deal with that. Signed-off-by: Eric Wong <normalperson@yhbt.net>
